3 Work around bug in CIFS and vboxsf file systems (Bug#13149).
4 The bug was observed on Ubuntu operating inside a virtual machine,
5 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
6 The workaround introduces a race condition on non-buggy hosts,
7 but it's an unlikely race and anyway there's a nearly identical
8 nearby race that can't be fixed.
9 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
11 (Fwrite_region): Test for file system time stamp bug.
12 (init_fileio): New function.

28 gap and end positions after each read and so help make_gap to work
29 properly. Do not signal an I/O error too early and so do not leave
30 not yet decoded characters in a buffer, which was the reason of
31 redisplay crash. Use list2 to build return value. Adjust comments.
33 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
35 Close a race when statting and reading files (Bug#13149).
36 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
37 This avoids a race if the file is renamed between stat and open.
38 This race is not the problem originally noted in Bug#13149;
39 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

487 * xdisp.c (message_dolog): Likewise.
489 2012-12-23 Eli Zaretskii <eliz@gnu.org>
491 * w32.c (acl_set_file): If setting the file security descriptor
492 fails, and the new DACL is identical to the existing one, silently
493 return success. This fixes problems for users backing up their
494 own files without having the necessary privileges for setting
495 security descriptors.
497 * w32proc.c (reader_thread): Do not index fd_info[] with negative
499 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
500 after WaitForSingleObject returns normally. This expedites reader
501 thread shutdown when delete_child triggers it.
502 (reap_subprocess): More accurate commentary for why we call
503 delete_child only when cp->fd is negative.
505 * w32.c (sys_close): Do not call delete_child on a subprocess
506 whose handle is not yet closed. Instead, set its file descriptor
507 to a negative value, so that reap_subprocess will call
508 delete_child on that subprocess when its SIGCHLD arrives.
509 This avoids closing handles used for communications between sys_select
510 and reader_thread, which doesn't give sys_select a chance to
511 notice that the process exited and invoke the SIGCHLD handler for
514 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
516 * nsfns.m (Fns_do_applescript): Run event loop until script has
517 been executed (Bug#12969).
518 (ns_run_ascript): Chech as_script for nil, set to nil after
521 2012-12-22 Martin Rudalics <rudalics@gmx.at>
523 * window.c (Fselect_window): Reword doc-string (Bug#13248).
525 2012-12-22 Eli Zaretskii <eliz@gnu.org>
527 * w32term.c (w32fullscreen_hook): New function.
528 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
530 2012-12-21 Eli Zaretskii <eliz@gnu.org>
532 * fileio.c (Finsert_file_contents): Doc fix.
534 * w32proc.c (new_child, delete_child, find_child_pid): For a
535 subprocess, consider its slot being in use as long as its process
536 handle (procinfo.hProcess) is not NULL. This avoids reusing the
537 slot when a new process is started immediately after killing
538 another one, without waiting enough time for the first process to
539 be reaped and resources allocated for it be orderly freed.
541 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
543 2012-12-21 Chong Yidong <cyd@gnu.org>
545 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
547 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
549 2012-12-21 Eli Zaretskii <eliz@gnu.org>
551 * w32.c (get_name_and_id): Always pass NULL as the first argument
552 of lookup_account_sid. Avoids crashes with UNC file names that
553 refer to DFS domains, not to specific machine names. (Bug#12621)
554 Remove now unused argument FNAME; all callers changed.
555 (get_file_owner_and_group): Remove now unused argument FNAME; all
558 2012-12-21 Chong Yidong <cyd@gnu.org>
560 * editfns.c (Finsert_char): Since read-char-by-name now signals an
561 error for invalid chars, don't check for a nil return value.
563 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
565 Avoid calls to CHAR_TO_BYTE if byte position is known.
566 * editfns.c (make_buffer_string_both): Use move_gap_both.
567 (Fbuffer_string): Use make_buffer_string_both.
568 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
570 (buf_bytepos_to_charpos): Likewise.
571 (charpos_to_bytepos): Remove.
572 * fileio.c (Finsert_file_contents): Use move_gap_both.
573 * search.c (Freplace_match): Likewise.
574 * process.c (process_send_region): Likewise. Use convenient
575 names for byte positions.
576 * lisp.h (charpos_to_bytepos): Remove prototype.
577 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
578 * insdel.c (move_gap): Likewise.
580 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
582 * xdisp.c (redisplay_internal): Remove now-unused local.
584 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
586 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
587 (redisplay_internal): Don't bother selecting the frame to get the
588 proper value of frame-local variables (bug#13225).
590 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
592 * textprop.c (set_text_properties_1): Do not allow NULL interval.
593 Rename 4th argument since it may be buffer or string. Adjust comment.
594 * intervals.c (graft_intervals_info_buffer): Find an interval here.
596 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
598 * coding.c (Fdetect_coding_region): Do not check start and end with
599 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
600 (code_convert_region): Likewise.
602 2012-12-18 Eli Zaretskii <eliz@gnu.org>
604 * w32.c (acl_get_file, acl_set_file): Run the file name through
605 map_w32_filename, and resolve any symlinks in the file name, like
607 (acl_set_file): Call revert_to_self, if any privileges were

613 ($(BLD)/w32.$(O)): Update dependencies.
615 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
617 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
618 propagate redisplay's scrolling (if any) to the right window.
619 (redisplay_internal): Use ensure_selected_frame.
620 (display_mode_lines): Complete last fix.
621 * window.c (select_window_1): New func, extracted from select_window.
622 (select_window): Use it.
623 * window.h (select_window_1): Declare.
625 2012-12-17 Eli Zaretskii <eliz@gnu.org>
627 Emulate Posix ACL APIs on MS-Windows.
628 * w32.c: Include sddl.h and sys/acl.h.

649 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
651 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
652 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
653 for some of that bug's symptoms can now cause Emacs to abort.
654 Remove the workaround.
655 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
656 The bug that caused SIGCHLD to get lost has been fixed, and the
657 workaround for it can now cause Emacs to abort.
659 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
661 * sysdep.c (emacs_abort): Bump backtrace size to 40.
662 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
663 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
665 2012-12-16 Romain Francoise <romain@orebokech.com>
667 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
668 (Fcopy_file): Change last arg to `preserve_extended_attributes'
669 and copy ACL entries of file in addition to SELinux context if set.
670 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
672 * Makefile.in (LIBACL_LIBS): New macro.
675 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
677 * fileio.c (internal_delete_file): Use bool for boolean.
679 2012-12-15 Eli Zaretskii <eliz@gnu.org>
681 Fix bug #13079 on MS-Windows with temp files not being deleted.
682 * w32.h (_child_process): New members input_file and
684 (register_child): First argument is now pid_t.
685 (record_infile, record_pending_deletion): New prototypes.
687 * w32proc.c (new_child): Initialize input_file and
688 pending_deletion members of the child.
689 (delete_child): Delete the child's temporary input file, if any,
690 that is pending deletion.
691 (register_child): First argument is now pid_t.
692 (record_infile, record_pending_deletion): New functions.
693 (reap_subprocess): Fix a typo in DebPrint string.
694 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
696 * fileio.c (internal_delete_file): Return an int again: non-zero
697 if delete-file succeeds, zero otherwise.
699 * lisp.h (internal_delete_file): Adjust prototype.
701 * callproc.c (Fcall_process): Don't overwrite infile with result
703 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
704 asynchronous subprocess, record the name of the input file name,
706 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
707 delete the file, record it as pending deletion when the subprocess
710 2012-12-14 Eli Zaretskii <eliz@gnu.org>
712 * editfns.c [HAVE_PWD_H]: Include grp.h.
714 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
716 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
718 Fix permissions bugs with setgid directories etc. (Bug#13125)
719 * dired.c (Ffile_attributes): Return t as the 9th attribute,
720 to mark it as a placeholder. The old value was often wrong.
721 The only user of this attribute has been changed to use
722 file-ownership-preserved-p instead, with its new group arg.
723 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

730 2012-12-14 Eli Zaretskii <eliz@gnu.org>
732 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
733 try to get accurate owner and group information from NT file
734 security APIs. This is to make most callers of 'stat' and
735 'lstat', which don't need that information, much faster.
737 * dired.c (Ffile_attributes) [WINDOWSNT]:
738 Set w32_stat_get_owner_group to a non-zero value, to request accurate
739 owner and group information from 'lstat'.
741 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
743 * fileio.c (Finsert_file_contents): Don't put tail into head area,
744 as that confuses set-auto-coding, so insist on the head-read
745 returning the full 1024 bytes. Let lseek compute the tail offset;
746 less work for us. Do not ignore I/O errors when reading the tail.
748 * xdisp.c: Minor style fixes.
749 (init_iterator): Hoist assignment out of if-expression.
750 (markpos_of_region): Callers now test for sign, not for -1.

767 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
769 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
770 files, fixing a regression from 24.2.
771 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
773 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
775 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
776 fstat shouldn't fail, and if it does fail copy-file should not proceed.
777 Remove unnecessary S_ISLNK test, as (contra the comments) this
778 function can't copy symlinks. Improve quality of error message
779 when attempting to copy files that are neither regular files nor
782 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

790 2012-12-12 Daniel Colascione <dancol@dancol.org>
792 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
793 the dumped Emacs is not a sparse file, greatly improving Cygwin
794 "make bootstrap" performance.
796 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
798 * inotify.c (inotify_callback): Generate an Emacs event for every
799 incoming inotify event.
801 2012-12-11 Eli Zaretskii <eliz@gnu.org>
803 * xdisp.c (handle_face_prop): Fix logic of computing
804 it->start_of_box_run_p.
805 (append_space_for_newline): If the glyph row is R2L, reset the
806 iterator's end_of_box_run_p flag before prepending the space glyph.
807 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
808 iterator's start_of_box_run_p flag before prepending the stretch.
809 (append_glyph, produce_image_glyph, append_composite_glyph)
810 (append_stretch_glyph, append_glyphless_glyph): Reverse the
811 left_box_line_p and right_box_line_p flags of the glyph for R2L
812 glyph rows. (Bug#13011)
814 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
816 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
817 if changed buffer is not shown in a window.

819 * window.c (replace_buffer_in_windows_safely): Do nothing
820 if buffer is not shown in a window.
821 (Fforce_window_update): Likewise if string or buffer argument
824 2012-12-11 Eli Zaretskii <eliz@gnu.org>
826 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
827 encoded_file_name, which is what it is.
829 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

853 Windows file notification functionality unless WINDOWSNT.
855 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
858 * w32fns.c (cache_system_info): Initialize the global hinst

861 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
862 (hinst): Remove unneeded extern declaration.
863 (_start): Remove initialization of above variables; remove
864 initialization of hinst, as cache_system_info now does that.
866 * emacs.c (main): Call cache_system_info early in startup; we
867 previously weren't calling it in Cygwin builds.
869 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):

991 * indent.c (Fvertical_motion): If a display string will be
992 displayed on the left or the right margin, don't consider it as a
993 factor in cursor positioning. (Bug#13108)
995 2012-12-10 Martin Rudalics <rudalics@gmx.at>
997 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
999 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
1001 * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int,
1004 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1006 * w32.c (unsetenv): Return 0 if the input string is too long.
1008 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1010 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1011 * alloc.c (xputenv): New function.
1012 * dbusbind.c (Fdbus_init_bus):
1014 * xterm.c (x_term_init):
1015 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1016 * editfns.c (initial_tz): Move static var decl up.
1017 (tzvalbuf_in_environ): New static var.
1018 (init_editfns): Initialize these two static vars.
1019 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1020 Save old TZ value on stack, if it's small.
1021 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1022 instead, use xputenv+unsetenv to set and restore TZ.
1023 (environbuf): Remove static var. All uses removed.
1024 (Fset_time_zone_rule): Do not save TZ and environ;
1025 no longer needed here.
1026 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1027 Move to inside set_time_zone_rule; they don't need file scope any more.
1028 (set_time_zone_rule): Maintain the TZ=value string separately.
1029 (syms_of_editfns): Don't initialize initial_tz;
1030 init_editfns now does it.
1031 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1032 * lisp.h (xputenv): New decl.
1034 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1036 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1038 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1040 * w32.c (unsetenv, sys_putenv): New functions.
1042 2012-12-08 Chong Yidong <cyd@gnu.org>
1044 * editfns.c (Finsert_char): Make the error message more
1045 informative (Bug#12992).
1047 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1049 Simplify get_lim_data.
1050 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1051 Remove USG and vlimit methods; no longer used these days.
1052 Add #error catchall just in case.
1054 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1055 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1056 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1057 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1058 (deleted_pid_list, Fdelete_process, create_process)
1059 (record_child_status_change, handle_child_signal, deliver_child_signal)
1060 (init_process_emacs, syms_of_process):
1061 Assume SIGCHLD is defined.
1062 (parse_signal): Remove. All uses removed.
1063 (abbr_to_signal): New static function.
1064 (Fsignal_process): Use it to convert signal names to ints.
1065 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1066 kill (getpgrp (), ...).
1067 (emacs_sigaction_init): Assume SIGCHLD is defined.
1068 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1069 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1070 * syssignal.h (EMACS_KILLPG): Remove.
1071 All uses replaced by 'kill' with a negative pid.
1072 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1073 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1075 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1077 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1078 This will cause a production Emacs to dump core instead of
1081 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1083 * frame.c (make_frame): Do not set window's buffer to t.
1084 * window.c (Fsplit_window_internal): Likewise. Previously it was
1085 used to indicate that the window is being set up. Now we use
1086 set_window_buffer for all new windows, so the condition in ...
1087 (Fset_window_buffer): ... is always true and can be removed.
1089 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1091 Convenient macro to check whether the buffer is hidden.
1092 * buffer.h (BUFFER_HIDDEN_P): New macro.
1093 * frame.c (make_frame): Use it. Adjust comment.
1094 * buffer.c (candidate_buffer): New function.
1095 (Fother_buffer, other_buffer_safely): Use it.
1097 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1099 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1100 if the child process is still running. Instead, exit the wait
1101 loop and return zero. (Bug#13086)
1103 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1105 * frame.h (x_char_width, x_char_height): Remove prototypes.
1106 * w32term.h (x_char_width, x_char_height): Likewise.
1107 * xfns.c (x_char_width, x_char_height): Remove.
1108 * w32fns.c (x_char_width, x_char_height): Likewise.
1109 * nsfns.c (x_char_width, x_char_height): Likewise.
1110 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for

1116 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1118 Fix a recently-introduced delete-process race condition.
1119 * callproc.c, process.h (record_kill_process):
1120 New function, containing part of the old call_process_kill.
1121 (call_process_kill): Use it.
1122 This does not change call_process_kill's behavior.
1123 * process.c (Fdelete_process): Use record_kill_process to fix a
1124 race condition that could cause Emacs to lose track of a child.
1126 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1128 Avoid code duplication between prev_frame and next_frame.
1129 * frame.c (candidate_frame): New function. Add comment.
1130 (prev_frame, next_frame): Use it. Adjust comment.
1132 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1134 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1135 fails, signal an error instead of continuing with an empty
1137 Encode expanded temp file pattern before passing it to mkstemp or
1140 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1141 Encode the file name before passing it to dostounix_filename, in
1142 case it will downcase it (under w32-downcase-file-names).
1145 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1147 Minor call-process cleanups.
1148 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1149 at the same time as other platforms, to simplify analysis.
1150 No need for fd0_volatile since we have synch_process_fd.
1151 Avoid needless emacs_close; arg is always negative.
1153 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1155 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1158 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1160 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1161 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1162 and mouse_face_hidden members to a bitfields.
1163 * frame.h (struct frame): Remove set-but-not-used space_width member.
1164 (FRAME_SPACE_WIDTH): Remove.
1165 * nsterm.m, w32term.c, xterm.c: Adjust users.
1166 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1167 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1168 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1169 members to a bitfields.
1171 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1173 Don't let call-process be a zombie factory (Bug#12980).
1174 Fixing this bug required some cleanup of the signal-handling code.
1175 As a side effect, this change also fixes a longstanding rare race
1176 condition whereby Emacs could mistakenly kill unrelated processes,
1177 and it fixes a bug where a second C-g does not kill a recalcitrant
1178 synchronous process in GNU/Linux and similar platforms.
1179 The patch should also fix the last vestiges of Bug#9488,
1180 a bug which has mostly been fixed on the trunk by other changes.
1181 * callproc.c, process.h (synch_process_alive, synch_process_death)
1182 (synch_process_termsig, sync_process_retcode):
1183 Remove. All uses removed, to simplify analysis and so that
1184 less consing is done inside critical sections.
1185 * callproc.c (call_process_exited): Remove. All uses replaced
1186 with !synch_process_pid.
1187 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1188 These take the role of what used to be in unwind-protect arg.
1190 (block_child_signal, unblock_child_signal):
1191 New functions, to avoid races that could kill innocent-victim processes.
1192 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1193 (call_process_kill): Record killed processes as deleted, so that
1194 zombies do not clutter up the system. Do this inside a critical
1195 section, to avoid a race that would allow the clutter.
1196 (call_process_cleanup): Fix code so that the second C-g works again
1197 on common platforms such as GNU/Linux.
1198 (Fcall_process): Create the child process in a critical section,
1199 to fix a race condition. If creating an asynchronous process,
1200 record it as deleted so that zombies do not clutter up the system.
1201 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1202 light of these changes. Omit unnecessary call to emacs_close
1203 before failure, as the unwind-protect code does that.
1204 * callproc.c (call_process_cleanup):
1205 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1206 * process.c (record_deleted_pid): New function, containing
1207 code refactored out of Fdelete_process.
1208 (Fdelete_process): Use it.
1209 (process_status_retrieved): Remove. All callers changed to use
1210 child_status_change.
1211 (record_child_status_change): Remove, folding its contents into ...
1212 (handle_child_signal): ... this signal handler. Now, this
1213 function is purely a handler for SIGCHLD, and is not called after
1214 a synchronous waitpid returns; the synchronous code is moved to
1215 wait_for_termination. There is no need to worry about reaping
1216 more than one child now.
1217 * sysdep.c (get_child_status, child_status_changed): New functions.
1218 (wait_for_termination): Now takes int * status and bool
1219 interruptible arguments, too. Do not record child status change;
1220 that's now the caller's responsibility. All callers changed.
1221 Reimplement in terms of get_child_status.
1222 (wait_for_termination_1, interruptible_wait_for_termination):
1223 Remove. All callers changed to use wait_for_termination.
1224 * syswait.h: Include <stdbool.h>, for bool.
1225 (record_child_status_change, interruptible_wait_for_termination):
1227 (record_deleted_pid, child_status_changed): New decls.
1228 (wait_for_termination): Adjust to API changes noted above.
1230 * bytecode.c, lisp.h (Qbytecode): Remove.
1231 No longer needed after 2012-11-20 interactive-p changes.
1233 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1235 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1236 the scroll margin, move point outside the margin. (Bug#13055)
1238 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1240 * gtkutil.c (my_log_handler): New function.
1241 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1243 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1245 * lisp.h (modify_region): Rename to...
1246 (modify_region_1): ...new prototype.
1247 * textprop.c (modify_region): Now static. Adjust users.
1248 * insdel.c (modify_region): Rename to...
1249 (modify_region_1): ...new function to work with current buffer.
1250 Adjust comment and users. Use true and false for booleans.
1252 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1254 * alloc.c (free_save_value): New function.
1255 (safe_alloca_unwind): Use it.
1256 * lisp.h (free_save_value): New prototype.
1257 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1259 (save_excursion_restore): Adjust to match saved data structure.
1260 Use free_save_value to offload some work from GC. Drop obsolete
1263 2012-12-03 Chong Yidong <cyd@gnu.org>
1265 * fileio.c (Vauto_save_list_file_name): Doc fix.
1267 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1269 * w32fns.c: Remove prototype of atof.
1270 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1272 (file_dialog_callback): Make it UINT_PTR.
1274 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1277 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1278 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1281 2012-12-03 Glenn Morris <rgm@gnu.org>
1283 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1285 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1287 Fix xpalloc confusion after memory is exhausted.
1288 * alloc.c (xpalloc): Comment fix.
1289 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1290 and signals an error, do not clear charset_table_size, as
1291 charset_table is still valid.
1292 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1294 Use execve to avoid need to munge environ (Bug#13054).
1295 * callproc.c (Fcall_process):
1296 * process.c (create_process):
1297 Don't save and restore environ; no longer needed.
1298 * callproc.c (child_setup):
1299 Use execve, not execvp, to preserve environ.
1301 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1303 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1305 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1307 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1308 display for sliced images (Bug#10500).
1310 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1312 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1314 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1315 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1317 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1319 * xdisp.c (window_outdated): Remove eassert since it hits
1320 some suspicious corner cases (see Bug#13007 and Bug#13012).
1321 (mode_line_update_needed): New function.
1322 (redisplay_internal, redisplay_window): Use it.
1323 (ensure_selected_frame): New function.
1324 (redisplay_internal, unwind_redisplay): Use it.
1325 (redisplay_internal): Move comment about buffer_shared...
1326 (buffer_shared_and_changed): ...near to its real use.
1328 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1330 * callproc.c (Fcall_process): Don't misreport vfork failure.
1332 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1334 * callproc.c (Fcall_process): Fix vfork portability problems.
1335 Do not assume that fd[0], count, filefd, and save_environ survive
1336 vfork. Fix bug whereby wrong errno value could be reported for
1337 pipe failure. Some minor cleanups, too, as follows. Move buf and
1338 bufsize to the context where they're needed. Change new_argv to
1339 be of type char **, as this is more convenient and avoids casts.
1340 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1341 Now local constants, not macros.
1343 2012-11-18 Kenichi Handa <handa@gnu.org>
1345 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1346 for the variable "f".
1348 2012-11-13 Kenichi Handa <handa@gnu.org>
1350 * font.c (font_unparse_xlfd): Exclude special characters from the
1351 generating XLFD name.
1353 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1355 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1357 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1359 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1363 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1364 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1365 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1366 * lread.c (readbyte_from_file): Assume EINTR is defined.
1367 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1368 Assume EIO and EAGAIN are defined.
1369 * unexcoff.c (write_segment): Assume EFAULT is defined.
1371 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1373 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1376 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1377 highlighting on the frame was cleared. Prevents assertion
1378 violations when repeatedly clicking on the "Top" link of the
1379 "bread-crumbs" in Info buffers.
1381 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1383 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1385 2012-11-24 Ken Brown <kbrown@cornell.edu>
1387 * keyboard.c (HAVE_MOUSE):
1388 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1389 were always defined.
1391 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1393 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1394 between bpos_covered and bpos_max. This fixes cursor display when
1395 several display strings follow each other.
1397 * .gdbinit (pgx): If the glyph's object is a string, display the
1398 pointer to string data, rather than the value of the string object
1399 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1401 * indent.c (Fvertical_motion): If the starting position is covered
1402 by a display string, return to one position before that, to avoid
1403 overshooting it inside move_it_to. (Bug#12930)
1405 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1407 * frame.h (struct frame): Remove display_preempted member
1408 since all users are dead long ago.

1410 * w32menu.c (pending_menu_activation): Remove since not
1412 (set_frame_menubar): Adjust user.
1413 * w32term.h (struct x_output): Drop outdated #if 0 code.
1414 (struct w32_output): Use bitfields for explicit_parent,
1415 asked_for_visible and menubar_active members.
1416 Drop unused pending_menu_activation member.
1417 * xterm.h (struct x_output): Drop outdated #if 0 code.
1418 Use bitfields for explicit_parent, asked_for_visible,
1419 has_been_visible and net_wm_state_hidden_seen members.
1421 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1423 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1424 of a literal "/". (Bug#12955)
1425 (gl-stamp): Invoke fc.exe directly, not through cmd.
1427 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1429 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1430 * dired.c: Assume HAVE_DIRENT_H.
1431 (NAMLEN): Remove, replacing with ...
1432 (dirent_namelen): New function. All uses changed. Use the GNU macro
1433 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1434 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1435 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1436 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1438 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1439 * ndir.h: Rename to ../nt/inc/dirent.h.
1440 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1441 Do not include <dirent.h>; no longer needed.
1442 * w32.c: Include <dirent.h> rather than "ndir.h".
1444 2012-11-23 Chong Yidong <cyd@gnu.org>
1446 * xftfont.c (xftfont_open): Remove duplicate assignment.
1448 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1450 * alloc.c (Fgarbage_collect): Unblock input after clearing
1451 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1452 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1453 * msdos.c (IT_frame_up_to_date): Use it here...
1454 * w32term.c (w32_frame_up_to_date): ...here...
1455 * xterm.c (XTframe_up_to_date): ...and here...
1456 * nsterm.m (ns_frame_up_to_date): ...but not here.
1457 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1459 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1460 Do not check whether GC is in progress.
1462 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1464 * xdisp.c (window_buffer_changed): New function.
1465 (update_menu_bar, update_tool_bar): Use it to
1466 simplify large 'if' statements.
1467 (redisplay_internal): Generalize commonly used
1468 'tail' and 'frame' local variables.
1470 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1472 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1473 with Windows system header.
1475 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1477 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1478 * alloc.c: Assume unistd.h exists.
1479 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1480 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1481 (getwd) [USG]: Remove; no longer needed.
1482 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1483 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1484 * w32.h (getcwd): Remove decl.
1486 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1488 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1489 Make it set selected_window as well.
1490 (update_tool_bar): Use it.
1492 2012-11-21 Ken Brown <kbrown@cornell.edu>
1494 * emacs.c (main): Set the G_SLICE environment variable for all
1495 Cygwin builds, not just GTK builds. See
1496 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1498 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1500 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1501 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1502 Define for the MSVC compiler.
1504 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1506 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1507 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1508 dostounix_filename. Prevents crashes down the road, because
1509 dostounix_filename assumes it gets a unibyte string.
1510 Reported by Michel de Ruiter <michel@sentient.nl>, see
1511 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1513 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1517 * lread.c (init_obarray): Set `function' fields to Qnil.
1518 * eval.c (Fcommandp): Ignore Qunbound.
1519 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1520 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1521 Test NILP rather than Qunbound.
1522 (Ffmakunbound): Set to Qnil.
1523 (Fsymbol_function): Never signal an error.
1524 (Finteractive_form): Ignore Qunbound.
1526 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1528 * eval.c (interactive_p): Remove no-longer-used decl.
1530 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1532 * xdisp.c (buffer_shared): Adjust comment.
1533 (buffer_shared_and_changed): New function.
1534 (prepare_menu_bars, redisplay_internal): Use it to
1535 decide whether all windows or frames should be updated.
1536 (window_outdated): New function.
1537 (text_outside_line_unchanged_p, redisplay_window): Use it.
1538 (redisplay_internal): Likewise. Fix indentation.
1540 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1542 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1543 (syms_of_eval): Remove corresponding defsubr.
1544 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1546 2012-11-19 Daniel Colascione <dancol@dancol.org>
1548 * w32fns.c (Fx_file_dialog):
1549 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1550 cygwin_convert_file_name*.
1552 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1553 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1555 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1557 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1559 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1561 * w32select.c: Include w32common.h before w32term.h, so that
1562 windows.h gets included before w32term.h uses some of its
1563 features, see below.
1565 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1567 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1569 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1571 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1573 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1574 (ns_select): Return at once if events are held (Bug#12834).
1576 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1578 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1579 Needed following 2012-10-20 change. (Bug#12902)
1581 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1583 * w32proc.c (waitpid): Remove unused label get_result.
1585 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1587 * makefile.w32-in (SYSWAIT_H): New macro.
1588 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1589 ($(BLD)/sysdep.$(O)): Update dependencies.
1591 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1593 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1594 * callproc.c (relocate_fd): Assume F_DUPFD.
1595 * emacs.c, term.c (O_RDWR): Remove.
1596 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1597 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1598 * nsterm.m: Assume <fcntl.h> exists.
1599 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1600 (create_pty, Fmake_network_process, server_accept_connection)
1601 (wait_reading_process_output, init_process_emacs):
1603 (wait_reading_process_output): Put in a special case for WINDOWSNT
1604 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1605 It's not clear this is needed, but it's a more-conservative change.
1606 (create_process): Assume FD_CLOEXEC.
1607 (create_process, create_pty): Assume O_NOCTTY.
1608 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1609 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1610 Omit if not DOS_NT, since F_GETFL is not defined there.
1611 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1612 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1614 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1615 lack it, since gnulib guarantees this.
1616 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1618 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1620 * w32.c (faccessat): Pretend that directories have the execute bit
1621 set. Emacs expects that, e.g., in files.el:cd-absolute.
1623 * w32proc.c (create_child): Don't clip the PID of the child
1624 process to fit into an Emacs integer, as this is no longer a
1626 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1627 reaping only the process specified by PID argument, if that is
1628 positive. Use PID instead of dead_child to know which process to
1629 reap. Wait for the child to die only if WNOHANG is not in
1631 (sys_select): Don't set dead_child.
1633 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1634 as it is no longer needed.
1636 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1638 (record_child_status_change): Remove the setting of
1639 record_at_most_one_child for the !WNOHANG case.
1641 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1643 Fix problems in ns port found by static checking.
1644 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1645 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1646 not to process group.
1647 (ns_select): Use emacs_write, not write, as that's more robust
1648 in the presence of signals.
1649 (fd_handler:): Check for read errors.
1651 2012-11-16 Glenn Morris <rgm@gnu.org>
1653 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1655 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1657 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1659 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1661 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1662 use the same value of thread handle.
1663 (start_timer_thread): If the timer thread exited (due to error),
1664 clean up by closing the two handles it used. Duplicate the caller
1665 thread's handle here, so it gets duplicated only once, when
1666 launching the timer thread. Set priority of the timer thread, not
1668 (getitimer): Don't duplicate the caller thread's handle here.
1671 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1673 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1676 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1678 Remove no-longer-used pty_max_bytes variable.
1679 * process.c (pty_max_bytes): Remove; unused.
1680 (send_process): Do not set it.
1682 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1684 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1685 Update dependencies.
1687 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1689 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1690 This follows up on the 2012-09-29 patch that removed indirection
1691 for the 'function' field. Reported by Sergey Vinokurov in
1692 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1694 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1696 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1697 different name, as the MS runtime does not have such a function,
1698 and probably never will.) All callers changed. Ignore DIRFD
1699 value if PATH is an absolute file name, to match Posix spec
1700 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1703 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1705 * xdisp.c (echo_area_display, redisplay_internal):
1706 Omit redundant check whether frame_garbaged is set.
1708 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1710 Use faccessat, not access, when checking file permissions (Bug#12632).
1711 This fixes a bug that has been present in Emacs since its creation.
1712 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1713 which must set some sort of record. (Torek's bug report was against
1714 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1715 same common flaw.) See Torek's Usenet posting
1716 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1717 Posted: Fri Apr 8 14:18:56 1983.
1718 * Makefile.in (LIB_EACCESS): New macro.
1720 * callproc.c (init_callproc):
1721 * charset.c (init_charset):
1722 * fileio.c (check_existing, check_executable, check_writable)
1724 * lread.c (openp, load_path_check):
1725 * process.c (allocate_pty):
1727 Use effective UID when checking permissions, not real UID.
1728 * callproc.c (init_callproc):
1729 * charset.c (init_charset):
1730 * lread.c (load_path_check, init_lread):
1731 Test whether directories are accessible, not merely whether they exist.
1732 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1733 * fileio.c (check_existing, check_executable, check_writable)
1735 Use symbolic names instead of integers for the flags, as they're
1737 (check_writable): New arg AMODE. All uses changed.
1738 Set errno on failure.
1739 (Ffile_readable_p): Use faccessat, not stat + open + close.
1740 (Ffile_writable_p): No need to call check_existing + check_writable.
1741 Just call check_writable and then look at errno. This saves a syscall.
1742 dir should never be nil; replace an unnecessary runtime check
1743 with an eassert. When checking the parent directory of a nonexistent
1744 file, check that the directory is searchable as well as writable, as
1745 we can't create files in unsearchable directories.
1746 (file_directory_p): New function, which uses 'stat' on most platforms
1747 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1748 (Ffile_directory_p, Fset_file_times): Use it.
1749 (file_accessible_directory_p): New function, which uses a single
1750 syscall for efficiency.
1751 (Ffile_accessible_directory_p): Use it.
1752 * xrdb.c (file_p): Use file_directory_p.
1753 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1754 * lread.c (openp): When opening a file, use fstat rather than
1755 stat, as that avoids a permissions race. When not opening a file,
1756 use file_directory_p rather than stat.
1757 (dir_warning): First arg is now a usage string, not a format.
1758 Use errno. All uses changed.
1759 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1760 that merely introduced a race.
1761 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1762 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1763 and similarly for the other O_* flags.
1764 * w32.c (sys_faccessat): Rename from sys_access and switch to
1765 faccessat's API. All uses changed.
1766 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1767 (magic_db): Rename from magic_file_p.
1768 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1769 char *, so that we don't have to test for file existence
1770 separately from opening the file for reading. This removes a race
1771 fixes a permission-checking problem, and simplifies the code.
1773 (file_p): Remove; no longer needed.
1775 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1777 Omit glyphs initialization at startup.
1778 * dispnew.c (glyphs_initialized_initially_p): Remove.
1779 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1780 (Fredraw_frame): Move actual code from here...
1781 (redraw_frame): ...to here. Add eassert. Adjust comment.
1782 (Fredraw_display): Use redraw_frame.
1783 * xdisp.c (clear_garbaged_frames): Likewise.
1785 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1787 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1788 passed to pint2str and pint2hrstr to be at most the size of the
1789 frame's decode_mode_spec_buffer. This avoids crashes with very
1790 large values of FIELD_WIDTH argument to decode_mode_spec.
1793 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1795 Fix a race with verify-visited-file-modtime (Bug#12863).
1796 Since at least 1991 Emacs has ignored an mtime difference of no
1797 more than one second, but my guess is that this was to work around
1798 file system bugs that were fixed long ago. Since the race is
1799 causing problems now, let's remove that code.
1800 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1801 whose time stamp is off by no more than a second. Insist that the
1802 file time stamps match exactly.
1804 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1806 * frame.h (struct frame): Convert external_tool_bar member to
1807 1-bit unsigned bitfield.
1808 * termhooks.h (struct terminal): Remove mouse_moved member since
1809 all users are long dead. Adjust comment on mouse_position_hook.
1811 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1813 Simplify by using FOR_EACH_FRAME here and there.
1814 * frame.c (next_frame, prev_frame, other_visible_frames)
1815 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1816 * w32term.c (x_window_to_scroll_bar): Likewise.
1817 * window.c (window_list): Likewise.
1818 * xdisp.c (x_consider_frame_title): Likewise.
1819 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1820 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1821 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1822 * xmenu.c (menubar_id_to_frame): Likewise.
1823 * xselect.c (frame_for_x_selection): Likewise.
1824 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1825 (x_window_to_menu_bar): Likewise.
1826 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1828 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1830 * data.c (Qdefalias_fset_function): Now static.
1832 Another tweak to vectorlike_header change.
1833 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1834 Remove, and replace all uses with ...
1835 (next_in_free_list, set_next_in_free_list):
1836 New functions, which respect C's aliasing rules better.
1838 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1840 * window.c (list4i): Rename from 'quad'. All uses changed.
1841 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1843 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1845 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1846 warning about mixing declarations and code in ISO C90.
1848 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1850 * window.c (Fsplit_window_internal): Set combination limit of
1851 new parent window to t iff Vwindow_combination_limit is t;
1852 fixing a regression introduced with the change from 2012-09-22.
1853 (Fset_window_combination_limit): Fix doc-string.
1855 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1857 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1858 amount when the scroll margins are too large. When scrolling
1859 backwards in the buffer, give up if cannot reach point or the
1860 scroll margin within a reasonable number of screen lines.
1861 Fixes point position in window under scroll-up/down-aggressively when
1862 point is positioned many lines beyond the window top/bottom.
1865 * ralloc.c (relinquish): If real_morecore fails to return memory
1866 to the system, don't crash; instead, leave the last heap
1867 unchanged and return. (Bug#12774)
1869 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1871 * lisp.h (AUTOLOADP): New macro.
1872 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1873 * data.c (Ffset): Remove special ad-advice-info handling.
1874 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1876 (Finteractive_form): Simplify.
1877 (Fquo): Don't insist on having at least 2 arguments.
1878 (Qdefalias_fset_function): New var.
1880 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1882 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1884 * nsfont.m (Qcondensed, Qexpanded): New variables.
1885 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1886 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1888 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1890 Fix recently introduced crash on MS-Windows (Bug#12839).
1891 * w32term.h (struct scroll_bar): Use convenient header.
1892 (SCROLL_BAR_VEC_SIZE): Remove.
1893 * w32term.c (x_scroll_bar_create): Use VECSIZE.

1897 Tweak last vectorlike_header change.
1898 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1899 vectorlike object on the free list. This is introduced to avoid

1934 special hash function containing a comparison that always yields 1.
1936 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1938 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1939 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1940 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1943 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1945 * image.c (xpm_make_color_table_h): Fix compiler error because
1946 make_hash_table changed.
1948 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1950 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1952 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1954 Use ad-hoc comparison function for the profiler's hash-tables.
1955 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1956 (make_log): Use them.

1967 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1968 (hash_lookup, hash_remove_from_table): Move assertion checking of
1969 hashfn result here. Check hash-equality before calling cmpfn.

1982 value of w32-scroll-lock-modifier is neither nil nor one of the
1983 known key modifiers. (Bug#12806)
1985 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1987 Shrink struct vectorlike_header to the only size field.
1988 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1990 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1991 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1992 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1993 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1994 information from the vector header. Adjust comment.

2016 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2017 Add easserts. Adjust XSETPVECTYPESIZE usage.
2018 (allocate_buffer): Use BUFFER_PVEC_INIT.
2019 (live_vector_p): Adjust to match large vector.
2020 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2021 * buffer.h (struct buffer): Add next member.

2032 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2034 * keyboard.c (event_to_kboard): Do not dereference
2035 frame_or_window field of SELECTION_REQUEST_EVENT

2037 * xterm.h (struct selection_input_event): Adjust comment.
2039 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2041 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2042 such as Scroll Lock, if the respective keys are treated as
2043 function keys, not as modifiers. This avoids destroying non-ASCII
2044 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2046 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2048 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2050 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2052 Restore some duplicate definitions (Bug#12814).
2053 This undoes part of the 2012-11-03 changes. Some people build
2054 with plain -g rather than with -g3, and they need the duplicate
2055 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2056 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2057 Define as macros, as well as as enums or as constants.
2059 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2061 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2062 to keypad keys (Bug#12816).
2064 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2066 Minor adjustments of recently-changed frame functions.
2067 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2068 known to be a frame (we're in the FRAMEP branch).
2069 * lisp.h (Qframep): Remove decl. frame.h declares this.
2070 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2071 since they're meant for Lisp fixnum values.
2073 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2075 * window.c (Fwindow_combination_limit): Revert to the only
2076 required argument and adjust docstring as suggested in
2077 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2078 by Martin Rudalics <rudalics@gmx.at>.
2080 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2082 Widely used frame validity and checking functions.
2083 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

2094 (frame_buffer_list, frame_buffer_predicate): Remove.
2095 * lisp.h (frame_buffer_predicate): Remove prototype.
2096 * buffer.c (Fother_buffer): Use decode_any_frame.
2097 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2098 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2099 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2100 (Fclose_font, Ffont_info): Use decode_live_frame.
2101 * fontset.c (check_fontset_name): Likewise.
2102 * terminal.c (Fframe_terminal): Likewise.
2103 * w32fns.c (check_x_frame): Likewise.
2104 * window.c (Fminibuffer_window, Fwindow_at)
2105 (Fcurrent_window_configuration): Likewise.
2106 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2107 Likewise. Allow zero number of arguments. Adjust docstring.
2108 * dispnew.c (Fredraw_frame): Likewise.
2109 * xfaces.c (frame_or_selected_frame): Remove.
2110 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2111 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2112 (Fframe_face_alist): Use decode_live_frame.
2113 * xfns.c (check_x_frame): Likewise.
2115 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2117 * window.c (quad): New function.
2118 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2119 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2120 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2121 (Fwindow_line_height): Use it.
2122 (Fwindow_fringes): Use list3.
2123 (Fwindow_scroll_bars): Use list4.
2124 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2125 (Fwindow_combination_limit): Allow zero number of arguments.
2127 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2129 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2131 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2132 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2133 file descriptor 2 for standard error. (Bug#12805)
2135 2012-11-05 Chong Yidong <cyd@gnu.org>
2137 * process.c (wait_reading_process_output): Revert previous change.
2139 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2141 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2142 This removes code that has been obsolete since around 1990.
2143 * callproc.c (Fcall_process):
2145 * process.c (create_process):
2146 * term.c (dissociate_if_controlling_tty):
2147 Assume setsid exists.
2148 * callproc.c (child_setup): Assume setpgid exists and behaves as
2149 per POSIX.1-1988 or later.
2150 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2151 * emacs.c (shut_down_emacs):
2152 * sysdep.c (sys_suspend, init_foreground_group):
2153 Assume getpgrp behaves as per POSIX.1-1998 or later.
2154 * msdos.c (setpgrp): Remove.
2155 (tcgetpgrp, setpgid, setsid): New functions.
2156 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2157 * term.c (no_controlling_tty): Remove; unused.
2158 * w32proc.c (setpgrp): Remove.
2159 (setsid, tcgetpgrp): New functions.
2161 Simplify by assuming __fpending.
2162 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2163 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2164 Do not assume that __fpending's result fits in int.
2166 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2168 Remove EMACS_OUTQSIZE+sleep hack.
2169 * dispnew.c (update_frame_1): Remove hack for terminals slower
2170 than 2400 bps, which throttled Emacs by having it sleep.
2171 This code hasn't worked since at least 2007, when the multi-tty stuff
2172 was added, and anyway those old terminals are long dead.
2173 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2174 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2176 Fix data-loss with --version (Bug#9574).
2177 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2178 as we can't assume that emacs_strerror is initialized, and strerror
2179 is good enough here.
2180 (main): Invoke atexit earlier, to catch earlier instances of
2181 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2183 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2185 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2186 (keyDown): Remap keypad keys to X11 virtual key codes.
2188 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2190 Fix data-loss with --batch (Bug#9574).
2191 * emacs.c: Include <close-stream.h>.
2192 (close_output_streams): New function.
2193 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2194 and handles errors appropriately.
2195 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2198 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2199 The symptom is a diagnostic "GLib-WARNING **: In call to
2200 g_spawn_sync(), exit status of a child process was requested but
2201 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2202 waitpid(), so exit status can't be returned." The diagnostic
2203 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2204 The real bug is a race condition between Emacs and glib: Emacs
2205 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2206 so that glib can't find it. Work around the bug by invoking
2207 waitpid only on subprocesses that Emacs itself creates.
2208 * process.c (create_process, record_child_status_change):
2209 Don't use special value -1 in pid field, as the caller now must
2210 know the pid rather than having the callee infer it.
2211 The inference was sometimes incorrect anyway, due to another race.
2212 (create_process): Set new 'alive' member if child is created.
2213 (process_status_retrieved): New function.
2214 (record_child_status_change): Use it.
2215 Accept negative 1st argument, which means to wait for the
2216 processes that Emacs already knows about. Move special-case code
2217 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2218 processes that have already been waited for, by testing and
2219 clearing new 'alive' member.
2220 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2221 now does this internally.
2222 (handle_child_signal): Let record_child_status_change do all
2223 the work, since we do not want to reap all exited child processes,
2224 only the child processes that Emacs itself created.
2225 * process.h (Lisp_Process): New boolean member 'alive'.
2227 Omit duplicate definitions no longer needed with gcc -g3.
2228 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2229 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2230 Define only as macros. There's no longer any need to also define
2231 these symbols as enums or as constants, since we now assume
2232 gcc -g3 when debugging.
2234 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2236 * lisp.mk: Adjust comments to the fact that term/internal is now
2237 loaded from loadup.el.
2239 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2240 (msdos_fatal_signal): New function.
2241 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2244 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2245 for GCC versions before 4.
2246 (emacs_raise): Define to call msdos_fatal_signal.
2248 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2249 iterator when starting in the middle of a display or overlay
2252 2012-11-03 Chong Yidong <cyd@gnu.org>
2254 * process.c (wait_reading_process_output): Clean up the last
2257 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2259 * process.c (wait_reading_process_output): Avoid a race condition
2260 with SIGIO delivery (Bug#11536).
2262 2012-11-03 Chong Yidong <cyd@gnu.org>
2264 * buffer.c (cursor_type): Untabify docstring.
2266 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2268 * frame.h (struct frame): Drop can_have_scroll_bars member
2269 which is meaningless for a long time. Adjust comments.
2270 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2271 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2273 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2275 * window.c (decode_next_window_args): Update window arg after
2276 calling decode_live_window and so fix crash reported at
2277 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2278 by Juanma Barranquero <lekktu@gmail.com>.
2279 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2280 * font.c (Ffont_at): Likewise.
2282 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2284 * widget.c (resize_cb): New function.
2285 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2286 (EmacsFrameResize): Check if all is up to date before changing frame
2289 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2291 Implement backtrace output for fatal errors on MS-Windows.
2292 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2293 (BACKTRACE_LIMIT_MAX): New macro.
2294 (w32_backtrace): New function.
2295 (emacs_abort): Use w32_backtrace when the user chooses not to
2296 attach a debugger. Update the text of the abort dialog.
2298 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2300 Window-related stuff cleanup here and there.
2301 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2302 Use decode_any_window.
2303 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2304 * xdisp.c (Fformat_mode_line): Likewise.
2305 * font.c (Ffont_at): Use decode_live_window.
2306 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2307 * window.c (decode_next_window_args): Likewise.
2308 (decode_any_window): Remove static.
2309 * window.h (decode_any_window): Add prototype.
2310 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2311 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2314 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2316 Remove pad from struct input_event.
2317 * termhooks.h (struct input_event): Remove padding field.
2319 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2320 member is never cons for a long time. Adjust comment.
2321 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2322 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2323 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2324 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2326 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2328 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2330 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2332 Fix crash when using Emacs as commit editor for git (Bug#12697).
2333 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2334 and it is configured in conf_post.h.
2335 (Fcall_process): Don't invoke both setsid and setpgid; the former
2336 is enough, if it exists.
2337 * callproc.c (Fcall_process, child_setup):
2338 * process.c (create_process): Use setpgid.
2339 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2341 * dispnew.c (init_display): Initialize the foreground group
2342 if we are running a tty display.
2343 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2344 * lisp.h (init_foreground_group): New decl.
2345 * sysdep.c (inherited_pgroup): New static var.
2346 (init_foreground_group, tcsetpgrp_without_stopping)
2347 (narrow_foreground_group, widen_foreground_group): New functions.
2348 (init_sys_modes): Narrow foreground group.
2349 (reset_sys_modes): Widen foreground group.
2351 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2353 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2355 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2357 * minibuf.c (read_minibuf): Restore current buffer since
2358 choose_minibuf_frame calling Fset_frame_selected_window may
2359 change it (Bug#12766).
2361 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2363 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2365 2012-10-30 Kenichi Handa <handa@gnu.org>
2367 * font.c (Ffont_at): If WINDOW is specified and it is not
2368 displaying the current buffer, signal an error.
2370 2012-10-29 Daniel Colascione <dancol@dancol.org>
2372 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2373 In preparation for fixing bug#12739, move these functions from
2376 * coding.h, coding.c: ... to here, and compile them only when
2377 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2378 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2380 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2382 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2383 (timer_loop, getitimer, setitimer): Use it instead of
2384 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2386 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2389 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2391 * nsterm.m (NO_APPDEFINED_DATA): New define.
2392 (last_appdefined_event_data): New variable
2393 (last_appdefined_event): Remove.
2394 (ns_select): Initialize t from last_appdefined_event_data instead
2395 of [last_appdefined_event data1].
2396 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2397 remove last_appdefined_event (Bug#12698).
2399 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2401 * frame.c (x_set_font): Catch internal error.
2403 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2405 Avoid overflow in w32 implementation of interval timers.
2406 When possible, for ITIMER_PROF count only times the main thread
2408 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2409 'volatile ULONGLONG' types. All the other data which was
2410 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2411 (GetThreadTimes_Proc): New typedef.
2412 (w32_get_timer_time): New function, returns a suitable time value
2414 (timer_loop): Enter critical section when accessing ULONGLONG
2415 values of the itimer_data struct, as these accesses are no longer
2416 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2417 Remove unused variable.
2418 (init_timers): Initialize s_pfn_Get_Thread_Times.
2419 (start_timer_thread): Don't assign itimer->caller_thread here.
2420 (getitimer): Assign itimer->caller_thread here.
2421 (setitimer): Always call getitimer to get the value of ticks_now.
2422 (sys_spawnve): Avoid compiler warning about format mismatch.
2424 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2426 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2427 mouse movement events if the menu bar is active. This avoids
2428 producing a busy "hour-glass" cursor by Windows if the mouse
2429 pointer is positioned over a tooltip shown for some menu item.
2431 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2433 Don't assume process IDs fit in int.
2434 * emacs.c (shut_down_emacs) [!DOS_NT]:
2435 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2436 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2437 Use pid_t, not int, to store process IDs, as 'int'
2438 is not wide enough on a few platforms (e.g., AIX and IRIX).
2440 2012-10-23 Kenichi Handa <handa@gnu.org>
2442 The following change is to make face-font-rescale-alist work
2443 correctly for non-ASCII fonts.
2445 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2446 (font_open_for_lface): Handle Vface_font_rescale_alist.
2448 2012-10-23 Chong Yidong <cyd@gnu.org>
2450 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2452 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2456 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2458 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2461 2012-10-21 Glenn Morris <rgm@gnu.org>
2463 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2465 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2467 Port to OpenBSD 5.1.
2468 * frame.c (Fmouse_position, Fmouse_pixel_position):
2469 * xdisp.c (produce_stretch_glyph):
2470 Declare local vars only when they're needed.
2471 This is clearer and avoids a warning on OpenBSD about unused vars.

2473 This is safer, and avoids OpenBSD warnings about unused vars.
2474 * keyboard.c (record_menu_key): Remove unnecessary decl.
2475 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2476 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2477 as our definition clashes with OpenBSD's.
2478 * xfaces.c (load_face_colors, check_lface_attrs)
2479 (get_lface_attributes_no_remap, get_lface_attributes)
2480 (lface_fully_specified_p, x_supports_face_attributes_p)
2481 (tty_supports_face_attributes_p, face_fontset, realize_face)
2482 (realize_x_face, realize_tty_face):
2483 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2484 merely Lisp_Object *. This is more informative and avoids
2485 a warning on OpenBSD about accessing beyond an object's size.
2487 2012-10-20 Chong Yidong <cyd@gnu.org>
2489 * lread.c (Fload): Doc fix (Bug#12592).

2515 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2516 (staticpro): If we run out of staticpro slots, die with an
2517 informative error instead of just calling emacs_abort.
2519 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2521 Fix two flaws reported by Dmitry Antipov.

2776 since unsigned is guaranteed to have that behavior and signed is not.

2778 (get_input_pending): Remove first argument, since it was always
2779 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2780 and behave as if it had that value. Return new value of
2781 input_pending. All callers changed.
2782 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2783 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2810 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2812 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2814 * commands.h (immediate_quit): Remove duplicate decl.
2816 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2818 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

2821 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2823 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2825 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2826 match what GetLastError returns. Explain why the function is
2829 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2830 'is_tooltip_frame', to avoid confusion with its global namesake.
2832 2012-10-08 Daniel Colascione <dancol@dancol.org>
2834 * xdisp.c (start_hourglass): Call w32_note_current_window when
2835 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2836 build that caused Emacs to display the hourglass cursor forever.
2838 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2839 which is broken under remote desktop, calculate the number of
2840 colors available for a display based on the display's number of
2841 planes and number of bits per pixel per plane. (bug#10397).
2843 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2845 * nsfont.m (Vfonts_in_cache): New variable.
2846 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2847 are used. Add cached fonts to Vfonts_in_cache.
2848 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2850 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2852 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2854 (FONT_H): Define after FRAME_H.
2855 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2856 Update dependencies.
2858 * w32term.c: Remove leftover declaration of keyboard_codepage.
2860 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2862 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2863 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2864 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2865 (GLOBAL_SOURCES): Add cygw32.c.
2866 ($(BLD)/unexw32.$(O)):
2868 ($(BLD)/w32console.$(O)):
2869 ($(BLD)/w32fns.$(O)):
2870 ($(BLD)/w32heap.$(O)):
2871 ($(BLD)/w32menu.$(O)):
2872 ($(BLD)/w32proc.$(O)): Add w32common.h.
2874 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2876 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2878 2012-10-08 Daniel Colascione <dancol@dancol.org>
2880 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2881 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2882 accidental message numbering hole. Change other messages to
2885 * w32select.h (HAVE_W32SELECT): Remove.
2887 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2888 w32common.h instead of w32heap.h.
2890 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2891 (get_allocation_unit, get_processor_type, get_w32_major_version)
2892 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2893 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2894 (OS_NT, os_subtype, cache_system_info): Move declarations to
2897 * w32heap.c: Include w32common.h.
2898 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2899 (w32_minor_version, w32_build_number, w32_subtype):
2900 Remove duplicate definitions.
2902 * w32fns.c: Include w32common.h; include w32heap.h only in
2905 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2906 Use `report_file_error' instead of `error' in order to better
2907 inform users of what went wrong. Increase NTGUI_UNICODE file
2908 dialog box file name length to 32k, the maximum allowed by the NT
2911 * w32common.h: New file.
2912 (ROUND_UP, ROUND_DOWN, get_page_size)
2913 (get_allocation_unit, get_processor_type, get_w32_major_version)
2914 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2915 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2916 (OS_NT, os_subtype, cache_system_info): Move here.
2918 * unexw32.c, unexcw.c: Include w32common.h.
2920 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2921 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2922 to call syms_of_w32select.
2924 * cygw32.h: Remove obsolete EXFUN declarations.
2926 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2928 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2929 of w32inevt.o from SOME_MACHINE_OBJECTS.
2931 2012-10-08 Daniel Colascione <dancol@dancol.org>
2933 * image.c: Permanent fix for JPEG compilation issue --- limit
2934 jpeglib `boolean' redefinition to Cygwin builds.
2936 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2938 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2940 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2943 2012-10-08 Daniel Colascione <dancol@dancol.org>
2945 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2946 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2947 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2948 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2949 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2950 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2951 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2952 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2953 now a supported configuration.
2955 * Makefile.in: consolidate image variables into LIBIMAGE; add
2956 W32_OBJ and W32_LIBS. Compile new files.
2959 (_DebPrint) declare tracing facility for W32 debugging. We need
2960 to unify tracing later.
2962 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2963 unconditional use of W32 Unicode functions. Cygwin runs only on
2964 100% Unicode operating systems.
2966 * cygw32.c: New file. Define Cygwin-specific facilities.
2967 (Fcygwin_convert_path_to_windows)
2968 (Fcygwin_convert_path_from_windows): New user functions for
2969 accessing Cygwin path-munging routines.
2971 * cygw32.h: New file.
2972 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2973 UTF-16LE strings temporarily inside non-Lisp-visible string
2976 (w32_strerror): Just what it says on the tin.
2978 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2979 also run for Cygwin; both systems have the same problem with using
2980 GUI facilities in a forked child. Also call syms_of_cygw32,
2981 syms_of_w32select in correct places.
2983 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2984 needs fork-then-exec for daemon launching.
2986 * font.h: Include frame.h.
2988 * image.c: Use the image library cache machinery only when we're
2989 compiling for native WINDOWSNT; Cygwin can use shared libraries
2990 like any other Unixlike system.
2992 * keyboard.c: Clarify a comment regarding the input loop.
2994 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2995 functions directly instead of trying to detect at runtime that our
2996 host operating system supports them. We make this change for two
2997 reasons: Cygwin lacks support for the multibyte character
2998 conversion functions used by the legacy menu code, and Cygwin
2999 never needs to rely on non-Unicode APIs.
3001 * unexw32.c (hinst): Declare extern.
3003 * w32.c: Change header order;
3004 (w32_strerror): Move to w32fns.c because we need it for
3005 non-WINDOWSNT builds.
3007 * w32.h: Add #error macro to make sure we don't include w32.h for
3008 Cygwin builds. Remove w32select declarations.
3010 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3011 w32fns.c. w32console.c is WINDOWSNT-only.
3013 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3014 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3016 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3017 (w32_major_version, w32_minor_version, w32_build_number)
3018 (os_subtype, sound_type): Define here
3019 (w32_defined_color): Make color parameter const for consistency
3020 with other _defined_color functions.
3021 (w32_createwindow): Unconditionally call w32_init_class instead of
3022 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3023 through the code is complex and unnecessary because class
3024 registration is practically free.
3025 (w32_name_of_message): New EMACSDEBUG-only function.
3026 (Fset_message_beep): Move here
3027 (Fx_open_connection): Require that the display name for Windows be
3028 "w32" for consistency, emacsclient disambiguation, and maybe, one
3029 day, multi-window-system support.
3030 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3031 Cygwin files for W32 GUI facilities, since these clearly don't
3032 expect Cygwin names.
3033 (_DebPrint): Define.
3034 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3035 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3036 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3037 (w32_last_error): Remove.
3039 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3041 * w32heap.c (syspage_mask): Declare here.
3042 (cache_system_info): Remove.
3044 * w32inevt.c (faked_key): Define globally, not statically.
3045 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3046 (w32_console_toggle_lock_key): Move to w32fns.c.
3048 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3050 * w32proc.c (_DebPrint): Move to w32fns.c.
3051 * w32select.c: Include string.h, stdio.h for Cygwin.
3052 * w32select.h: New File.
3054 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3056 (w32_message_fd): New variable. Under Cygwin, holds the file
3057 descriptor the system used to tell us about pending thread
3060 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3061 that prevented compilation under non-WINDOWSNT systems.
3063 (w32_initialize): Open /dev/windows and assign it to
3064 w32_message_fd. Provide w32 feature.
3066 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3067 (WM_EMACS_INPUT_READY): add.
3068 (prepend_msg, w32_message_fd): Declare globally.
3071 (keyboard_handle): Use only when WINDOWSNT.
3072 (notify_msg_ready): New function. Posts a message to the main
3073 thread's message queue under CYGWIN, which wakes up the main
3074 thread from select(2) by making the /dev/windows file descriptor
3075 ready. Under WINDOWSNT, it sets an event the same way the old
3078 (post, prepend_msg): Actually call notify_msg_ready instead of
3079 setting the input event directly.
3081 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3083 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3084 but it still has blocs in it, don't return it to the system,
3085 instead of aborting. (Bug#12402)
3087 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3089 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3091 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3092 MAC_OS_X_VERSION_10_6.
3093 (syms_of_nsterm): Remove comment about Panther and above for
3095 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3096 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3097 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3099 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3100 MAC_OS_X_VERSION_10_4.
3102 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3103 MAC_OS_X_VERSION_10_2.
3105 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3107 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3108 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3110 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3111 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3112 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3113 Remove ns_in_resize check.
3114 (ns_clear_frame_area): Remove resize handle code.
3116 * nsfns.m (ns_in_resize): Remove.
3117 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3118 Remove ns_in_resize check.
3120 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3122 Improve sys_siglist detection.
3123 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3124 defined as a macro, as is done in Solaris.
3125 (sys_siglist_entries): New macro.
3126 (save_strsignal): Use it.
3127 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3128 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3130 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3132 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3133 fullscreen/Fullscreen.
3135 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3136 tobar_height is new.
3138 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3139 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3140 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3141 (windowDidResize:): Check for correct window if old style fullscreen.
3142 Capitalize word in comment. Remove incorrect comment.
3143 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3144 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3145 error in drawing background.
3146 (toggleFullScreen:): Remove comment. Rearrange calls.
3147 Set toolbar values to zero, save old height in tobar_height.
3148 Restore tool bar height when leaving fullscreen.
3149 (canBecomeMainWindow): New function.
3151 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3153 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3155 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3157 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3159 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3160 that time stamps of directories could also be changed.
3161 Don't request the too broad GENERIC_WRITE, only the more restrictive
3162 FILE_WRITE_ATTRIBUTES access rights.
3164 * fileio.c (Fset_file_times): Special-case ignoring errors for
3165 directories only on MSDOS, not on MS-Windows.
3167 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3169 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3171 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3173 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3174 see whether CreateFile failed.
3176 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3178 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3179 to avoid similar races.
3180 * keyboard.c (pending_signals): Now bool, not int.
3182 Port timers to OpenBSD, plus check for timer failures.
3183 OpenBSD problem reported by Han Boetes.
3184 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3186 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3187 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3188 like OpenBSD, which has timer_settime but does not declare it.
3189 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3190 whether to use itimerspec-related primitives. All uses of
3191 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3193 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3195 * profiler.c (handle_profiler_signal): Fix a malloc race
3196 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3198 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3200 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3202 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3204 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3205 consistent with the change in return value of 'safe_strsignal'.
3207 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3209 Prefer plain 'static' to 'static inline' (Bug#12541).
3210 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3211 (bidi_set_sor_type, bidi_push_embedding_level)
3212 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3213 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3214 (bidi_cache_search, bidi_cache_ensure_space)
3215 (bidi_cache_iterator_state, bidi_cache_find)
3216 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3217 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3218 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3219 Now 'static', not 'static inline'.
3221 Count overruns when profiling; change units to ns.
3222 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3223 Give extra weight to samples after overruns, to attempt to count
3224 the time more accurately.
3225 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3226 the underlying primitives nominally do ns.
3227 (Fprofiler_cpu_start): Document the change. Mention that
3228 the sampling intervals are only approximate.
3230 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3232 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3234 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3235 case for the special 0 coding-system.
3237 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3238 (Fmake_overlay): Remove redundant tests.
3239 (fix_start_end_in_overlays): Remove redundant recentering.
3241 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3243 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3244 Update dependencies.
3246 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3248 Fix a malloc race condition involving strsignal.
3249 A signal can arrive in the middle of a malloc, and Emacs's signal
3250 handler can invoke strsignal, which can invoke malloc, which is
3251 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3252 Fix it by altering the signal handler so that it does not invoke
3254 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3255 * process.c (status_message): Use const pointer, in case strsignal
3256 is #defined to safe_strsignal.
3257 * sysdep.c (sys_siglist, init_signals): Always define and
3258 initialize a substitute sys_siglist if the system does not define
3259 one, even if HAVE_STRSIGNAL.
3260 (safe_strsignal): Rename from strsignal. Always define,
3261 using sys_siglist. Return a const pointer.
3262 * syssignal.h (safe_strsignal): New decl.
3263 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3265 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3267 * w32proc.c (timer_loop): Fix code that waits for timer
3268 expiration, to avoid high CPU usage.
3270 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3272 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3273 (sweep_weak_table): Remove redundant prototypes.
3275 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3277 * emacs.c: Move the inclusion of TERM_HEADER after including
3278 windows.h on WINDOWSNT. This avoids compilation problems with
3281 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3283 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3284 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3285 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3286 as the previous version used 'void *'.
3288 * ralloc.c (ROUNDUP): Fix last change.
3289 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3292 * w32proc.c <disable_itimers>: New static flag.
3293 (init_timers): Initialize it to zero, after creating the critical
3294 sections used by the timer threads.
3295 (term_timers): Set to 1 before deleting the critical sections.
3296 (getitimer, setitimer): If disable_itimers is non-zero, return an
3297 error indication without doing anything. Reported by Fabrice
3298 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3299 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3301 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3304 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3305 term_ntproc after all the other bookkeeping, to get timers working
3306 as long as possible.
3308 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3310 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3311 Suggested by Juri Linkov in
3312 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3314 Prefer plain 'static' to 'static inline' (Bug#12541).
3315 With static functions, modern compilers inline pretty well by
3316 themselves; advice from programmers often hurts as much as it helps.
3317 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3318 this change shrinks the text size of the Emacs executable by 1.1%
3319 without affecting CPU significantly in my benchmark.
3320 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3399 (bidi_copy_it): Do the whole copy with a single memcpy.
3400 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3402 Revert the FOLLOW-SYMLINKS change for file-attributes.
3403 Doing it right would require several changes to Tramp, and there's
3404 not enough time to get that tested before the freeze today.
3405 * dired.c (directory_files_internal, Ffile_attributes):
3408 * frame.c (x_report_frame_params): Port better to wider ints.
3409 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3410 or that pointers can be printed in 15 decimal digits.
3411 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3447 * vm-limit.c (lim_data): Now size_t.
3448 (check_memory_limits): Adjust prototypes of real_morecore and
3449 __morecore to receive argument of type ptrdiff_t. Use size_t for

3503 sigfillset, and sigprocmask are no longer no-ops.
3504 (sigismember): New function.
3505 (struct itimer_data): New definition.
3506 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)
3507 (crit_prof): New static variables.

3513 * w32.c (term_ntproc): Call term_timers.
3514 (init_ntproc): Make sure all signals are unblocked at startup, to
3515 erase any traces of dumping. Call init_timers.

3518 Windows-specific code to display the hourglass mouse pointer is no
3520 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
3521 to hourglass timer expiration.

3603 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3604 signal.h, setjmp.h. Include systime.h instead.
3605 (saturated_add): New function.

3612 All uses changed to store the new value.
3613 (handle_profiler_signal): Rename from sigprof_handler_1,
3614 for consistency with other handlers. Do not check whether
3615 cpu_log is a hash-table if garbage collecting, since it
3616 doesn't matter in that case.

3618 for consistency with other handlers.
3619 (setup_cpu_timer): New function, with much of what used to be in
3620 Fprofiler_cpu_start. Check for out-of-range argument.
3621 Prefer timer_settime if available, and prefer
3622 thread cputime clocks, then process cputime clocks, then
3623 monotonic clocks, to the old realtime clock. Use make_timeval
3624 to round more-correctly when falling back to setitimer.
3625 (Fprofiler_cpu_start): Use it.
3626 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3627 Don't assume that passing NULL as the 2nd argument of setitimer
3628 is the same as passing a pointer to all-zero storage.
3629 Ignore SIGPROF afterwards.
3630 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3631 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3632 non-fatal signal handlers. Ignore SIGPROF on startup.
3633 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3634 in profiler.c, since sysdep.c now uses it.
3636 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3658 2012-09-28 Eli Zaretskii <eliz@gnu.org>
3660 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
3661 Qautomatic_redisplay and change the symbol name. All users changed.
3663 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
3665 * profiler.c (sigprof_handler): Fix race condition.

3671 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
3673 Check more robustly for timer_settime.
3674 * Makefile.in (LIB_TIMER_TIME): New macro.
3676 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
3677 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
3680 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
3682 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

3690 * character.h (MAYBE_UNIFY_CHAR): Remove.
3691 * charset.c, charset.h (maybe_unify_char): Now static.
3692 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3693 Since this stuff is now private to charset.c, there's no need for
3694 a public macro and no need to inline by hand.

3722 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3723 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3725 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
3727 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
3729 Prefer POSIX timers if available.
3730 They avoid a race if the timer is too close to the current time.
3731 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
3732 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
3733 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
3735 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3737 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
3738 CHAR_STRING_ADVANCE.
3739 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
3740 STRING_CHAR_ADVANCE.
3742 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3744 Move Vlibrary_cache to emacs.c and reset before dumping.
3746 * lisp.h (reset_image_types): Declare.
3747 [WINDOWSNT] (Vlibrary_cache): Declare.
3749 * image.c (reset_image_types): New function.
3751 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
3752 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.

3758 * w32.h (Vlibrary_cache): Do not declare.
3760 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3762 * w32proc.c (sys_signal): Handle all signals defined by the
3763 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3764 handlers for signals supported by Windows. Don't override
3765 term_ntproc as the handler for SIGABRT.
3766 (sigaction): Rewrite to call sys_signal instead of duplicating its
3768 (sys_kill): Improve commentary.
3770 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3771 consistency with a signature of a signal handler. All callers
3773 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3774 install term_ntproc as a signal handler for SIGABRT, as that
3775 should be done by the dumped Emacs.
3777 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3779 * w32select.c (term_w32select): Protect against repeated
3780 invocation by setting clipboard_owner to NULL after calling

3784 and term_ntproc to their modified signatures.
3786 * character.c (char_string, string_char): Remove calls to
3787 MAYBE_UNIFY_CHAR. See the discussion starting at
3788 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
3791 2012-09-25 Chong Yidong <cyd@gnu.org>
3793 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
3795 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3797 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3798 when encountering an unknown bytecode.
3800 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3802 image.c, indent.c: Use bool for booleans.
3803 * dispextern.h (struct image_type): Members valid_p, load, init
3804 now return bool, not int. All uses changed.
3805 * image.c: Omit unnecessary static decls.
3806 (x_create_bitmap_mask, x_build_heuristic_mask):
3807 Return void, not int, since callers don't care about the return value.

3836 Use bool for booleans.
3838 2012-09-24 Chong Yidong <cyd@gnu.org>
3840 * chartab.c (Fset_char_table_default): Obsolete function removed.
3842 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3844 Move pid_t related decls out of lisp.h.
3845 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3846 (interruptible_wait_for_termination):
3847 Move these decls from lisp.h to syswait.h, since they use pid_t.
3848 Needed on FreeBSD; see Herbert J. Skuhra in
3849 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3850 * callproc.c: Include syswait.h.

3867 * nsmenu.m (ns_update_menubar):
3868 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
3869 * xfns.c (Fx_show_tip) [USE_GTK]:
3870 Use bool for boolean.
3871 * gtkutil.c (xg_update_frame_menubar):
3872 * xmenu.c (update_frame_menubar):
3873 Return void, not int, since caller ignores return value.
3874 * gtkutil.c (xg_change_toolbar_position):
3877 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3879 * makefile.w32-in (BLOCKINPUT_H): Remove.

3896 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3898 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3899 fatal_error_backtrace.
3901 * w32proc.c (sys_kill): Undo last change: don't do anything when
3902 invoked to deliver SIGABRT to our own process. This is now
3903 handled by emacs_raise.
3905 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3907 * w32term.c (w32_read_socket): Remove leftover reference to
3908 interrupt_input_pending.
3910 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3912 Do not use SA_NODEFER.
3913 Problem reported by Dani Moncayo in
3914 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3916 * sysdep.c (emacs_abort): Do not reset signal handler.
3917 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3918 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3919 wanted even on POSIXish hosts, and it doesn't work on Windows.
3921 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3923 * xterm.c (x_term_init): Call fixup_locale before and after calling
3924 gtk_init (Bug#12392).
3926 2012-09-23 Chong Yidong <cyd@gnu.org>
3928 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3929 Vdynamic_library_alist.
3931 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3932 (Fgnutls_available_p): Caller changed.
3934 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3935 (Flibxml_parse_xml_region): Likewise.
3937 * dispextern.h (struct image_type): Remove arg from init function.
3939 * image.c (Finit_image_library, lookup_image_type)
3940 (define_image_type): Remove now-unneeded second arg.
3941 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3942 (init_tiff_functions, init_gif_functions, init_svg_functions):
3943 Arglist and w32_delayed_load calling convention changed.
3944 (gs_type): Remove init_gs_functions; there is no such function.
3945 (valid_image_p, make_image): Fix caller to lookup_image_type.
3947 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3949 Simplify and avoid signal-handling races (Bug#12471).
3951 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3952 Avoid recursive loop if there's a fatal error in the function itself.
3953 * atimer.c (pending_atimers):
3954 * blockinput.h: Don't include "atimer.h"; no longer needed.
3955 (interrupt_input_pending): Remove. All uses removed.
3956 pending_signals now counts both atimers and ordinary interrupts.
3957 This is less racy than having three separate pending-signal flags.
3958 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3960 Rename from their upper-case counterparts BLOCK_INPUT,
3961 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3962 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3963 This makes it easier to access volatile variables more accurately.
3964 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3965 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3966 that's more reliable if the code is buggy and sets
3967 interrupt_input_blocked to a negative value. All uses changed.
3968 * atimer.c (deliver_alarm_signal):
3969 Remove. No need to deliver this to the parent; any thread can
3970 handle this signal now. All uses replaced by underlying handler.
3971 * atimer.c (turn_on_atimers):
3972 * dispnew.c (handle_window_change_signal):
3973 * emacs.c (handle_danger_signal):
3974 * keyboard.c (kbd_buffer_get_event):
3975 Don't reestablish signal handler; not needed with sigaction.
3976 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3978 Rework to avoid unnecessary accesses to volatile variables.
3979 (UNBLOCK_INPUT_TO): Now a function.
3980 (totally_unblock_input, unblock_input): New decls.
3981 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3982 (init_data): Remove. Necessary stuff now done in init_signal.
3983 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3984 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3985 (fatal_error_code): Remove; no longer needed.
3986 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3987 it doesn't always backtrace. All uses changed. No need to reset
3988 signal to default, since sigaction and/or die does that for us now.
3989 Use emacs_raise (FOO), not kill (getpid (), FOO).
3990 (main): Check more-accurately whether we're dumping.
3991 Move fatal-error setup to sysdep.c
3992 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3993 * gtkutil.c (xg_get_file_name, xg_get_font):
3994 Remove no-longer-needed signal-mask manipulation.
3995 * keyboard.c, process.c (POLL_FOR_INPUT):
3996 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3997 * keyboard.c (read_avail_input): Remove.
3998 All uses replaced by gobble_input.
3999 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4000 (kbd_buffer_store_event_hold, gobble_input):
4001 (record_asynch_buffer_change) [USABLE_SIGIO]:
4002 (store_user_signal_events):
4003 No need to mess with signal mask.
4004 (gobble_input): If blocking input and there are terminals, simply
4005 set pending_signals to 1 and return. All hooks changed to not
4006 worry about whether input is blocked.
4007 (process_pending_signals): Clear pending_signals before processing
4008 them, in case a signal comes in while we're processing.
4009 By convention callers now test pending_signals before calling us.
4010 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4011 New functions, to support changes to blockinput.h.
4012 (handle_input_available_signal): Now extern.
4013 (reinvoke_input_signal): Remove. All uses replaced by
4015 (quit_count): Now volatile, since a signal handler uses it.
4016 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4017 All callers changed. Block SIGINT only if not already blocked.
4018 Clear sigmask reliably, even if Fsignal returns, which it can.
4019 Omit unnecessary accesses to volatile var.
4020 (quit_throw_to_read_char): No need to restore sigmask.
4021 * keyboard.c (gobble_input, handle_user_signal):
4022 * process.c (wait_reading_process_output):
4023 Call signal-handling code rather than killing ourselves.
4024 * lisp.h: Include <float.h>, for...
4025 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4026 (pending_signals): Now volatile.
4027 (syms_of_data): Now const if IEEE floating point.
4028 (handle_input_available_signal) [USABLE_SIGIO]:
4029 (terminate_due_to_signal, record_child_status_change): New decls.
4030 * process.c (create_process): Avoid disaster if memory is exhausted
4031 while we're processing a vfork, by tightening the critical section
4033 (send_process_frame, process_sent_to, handle_pipe_signal)
4034 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4036 (send_process): No need for setjmp/longjmp any more, since the
4037 SIGPIPE stuff is now gone. Instead, report an error if errno
4039 (record_child_status_change): Now extern. PID and W are now args.
4040 Return void, not bool. All callers changed.
4041 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4042 Remove. All uses removed. This bug should be fixed now in a
4044 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4045 and record the child status change directly. This avoids the
4046 need to futz with the signal mask.
4047 (process_fatal_action): Move here from emacs.c.
4048 (emacs_sigaction_flags): New function, containing
4049 much of what used to be in emacs_sigaction_init.
4050 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4051 caught by emacs, to make races less likely.
4052 (deliver_process_signal): Rename from handle_on_main_thread.
4054 (BACKTRACE_LIMIT_MAX): Now at top level.
4055 (thread_backtrace_buffer, threadback_backtrace_pointers):
4057 (deliver_thread_signal, deliver_fatal_thread_signal):
4058 New functions, for more-accurate delivery of thread-specific signals.
4059 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4060 (deliver_arith_signal): Handle in this thread, not
4061 in the main thread, since it's triggered by this thread.
4062 (maybe_fatal_sig): New function.
4063 (init_signals): New arg DUMPING so that we can be more accurate
4064 about whether we're dumping. Caller changed.
4065 Treat thread-specific signals differently from process-general signals.
4066 Block all signals while handling fatal error; that's safer.
4067 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4069 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4070 Ignore SIGPIPE unless batch.
4071 (emacs_backtrace): Output backtrace for the appropriate thread,
4072 which is not necessarily the main thread.
4073 * syssignal.h: Include <stdbool.h>.
4074 (emacs_raise): New macro.
4075 * xterm.c (x_connection_signal): Remove; no longer needed
4076 now that we use sigaction.
4077 (x_connection_closed): No need to mess with sigmask now.
4078 (x_initialize): No need to reset SIGPIPE handler here, since
4079 init_signals does this for us now.
4081 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4083 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4084 background rect may be larger (Bug#12245).
4086 2012-09-23 Chong Yidong <cyd@gnu.org>
4088 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4090 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4092 * .gdbinit: Just stop at fatal_error_backtrace.
4093 See Stefan Monnier's request in
4094 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4095 Remove no-longer-used query of system type.
4097 2012-09-22 Chong Yidong <cyd@gnu.org>
4099 * search.c (Freplace_match): Doc fix (Bug#12325).
4101 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4103 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4104 (Fline_end_position): Doc fix.
4106 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4108 2012-09-22 Chong Yidong <cyd@gnu.org>
4110 * dispextern.h (struct image_type): Add new slot, storing a type
4111 initialization function.
4113 * image.c (define_image_type): Call the image initializer function
4114 if it is defined. Arguments and return value changed.
4115 (valid_image_p, make_image): Callers changed.
4116 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4117 (gif_type, imagemagick_type, svg_type, gs_type):
4118 Add initialization functions.
4119 (Finit_image_library): Call lookup_image_type.
4120 (CHECK_LIB_AVAILABLE): Macro deleted.
4121 (lookup_image_type): Call define_image_type here, rather than via
4122 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4123 (syms_of_image): Move define_image_type calls for xbm_type and
4124 pbm_type to lookup_image_type.
4126 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4128 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4129 'idle_timers' from here ...
4130 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4131 lists, to avoid infloops when the timer does something stupid,
4132 like reinvoke itself with the same or smaller time-out.
4135 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4137 * window.c (Fsplit_window_internal): Handle only Qt value of
4138 Vwindow_combination_limit separately.
4139 (Qtemp_buffer_resize): New symbol.
4140 (Vwindow_combination_limit): New default value.
4143 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4145 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4146 the new overlay string. (Bug#10159)
4148 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4150 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4151 or that fprintf is async-signal-safe. POSIX doesn't require
4154 2012-09-22 Chong Yidong <cyd@gnu.org>
4156 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4159 2012-09-22 Kenichi Handa <handa@gnu.org>
4161 * composite.c (composition_reseat_it): Handle the case that a
4162 grapheme cluster is not covered by a single font (Bug#12352).
4164 2012-09-21 Chong Yidong <cyd@gnu.org>
4166 * image.c (define_image_type): Avoid adding duplicate types to
4167 image_types (Bug#12463). Suggested by Jörg Walter.
4169 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4171 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4172 (print_load_command_name): Add case LC_DATA_IN_CODE.
4173 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4175 2012-09-21 Glenn Morris <rgm@gnu.org>
4177 * eval.c (Frun_hook_with_args_until_success)
4178 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4180 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4182 * fileio.c (Ffile_selinux_context): Only call freecon when
4183 lgetfilecon succeeded.
4184 (Fset_file_selinux_context): Likewise. (Bug#12444)
4186 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4188 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4189 reordering, locate the cursor by calling set_cursor_from_row; if
4190 that fails, clear the desired glyph matrix before returning a
4191 failure indication to the caller. Fixes leaving garbled display
4192 when fast scrolling with a down-key. (Bug#12403)
4193 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4194 scrolling through multibyte text.
4196 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4198 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4199 calling mark_vectorlike since that's the one that marks the window.
4200 (mark_discard_killed_buffers): Mark the final cdr.
4201 * window.h (struct window): Move prev/next_buffers to the
4202 non-standard fields.
4203 * window.c (make_window): Initialize prev/next_buffers manually.
4205 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4207 Omit unused arg EXPECTED from socket hooks.
4208 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4209 * nsterm.m (ns_term_init):
4210 * termhooks.h (struct terminal.read_socket_hook):
4211 * w32inevt.c (w32_console_read_socket):
4212 * w32term.c (w32_read_socket):
4213 * xterm.c (XTread_socket):
4214 Omit unused arg EXPECTED. All callers changed.
4215 (store_user_signal_events): Return void, not int, since callers no
4216 longer care about the return value. All uses changed.
4218 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4220 * w32gui.h (XParseGeometry): Do not declare.
4222 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4224 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4225 Ignore 'expected'. See Eli Zaretskii in
4226 <http://bugs.gnu.org/12471#8> (last line).
4228 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4229 (XParseGeometry): Now static. Substitute extremal values for
4230 values that are out of range.
4232 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4234 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4236 * nsfns.m (XParseGeometry): Remove.
4237 (Fx_create_frame): Call x_set_offset to correctly interpret
4238 top_pos in geometry.
4240 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4241 (Fx_parse_geometry): If there is a space in string, call
4242 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4244 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4246 * search.c (scan_buffer): Use character positions in calls to
4247 region_cache_forward and region_cache_backward, not byte
4248 positions. (Bug#12196)
4250 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4251 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4253 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4254 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4255 emacs_blocked_malloc, now deleted.
4257 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4259 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4260 The workaround was for improving performance on Solaris 2.4, but
4261 is getting in the way now. Emacs will still work if someone is
4262 still running Solaris 2.4 in a museum somewhere; Sun dropped
4263 support for Solaris 2.4 in 2003.
4264 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4265 * process.c (create_process) [HAVE_WORKING_VFORK]:
4266 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4267 since Emacs no longer uses vfork on that platform.
4269 2012-09-17 Glenn Morris <rgm@gnu.org>
4271 * emacs.c: Use COPYRIGHT.
4273 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4275 Remove configure's --without-sync-input option (Bug#12450).
4276 When auditing signal-handling in preparation for cleaning it up,
4277 I found that SYNC_INPUT has race conditions and would be a real
4278 pain to fix. Since it's an undocumented and deprecated
4279 configure-time option, now seems like a good time to remove it.
4280 Also see <http://bugs.gnu.org/11080#16>.
4281 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4282 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4283 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4284 (malloc_hysteresis):
4285 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4286 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4287 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4288 (dont_register_blocks, bytes_used_when_reconsidered)
4289 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4290 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4291 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4292 Remove. All uses removed.
4293 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4294 implementation, one that depends on whether the new macro
4295 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4297 * atimer.c (run_timers, handle_alarm_signal):
4298 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4299 (handle_async_input, process_pending_signals)
4300 (handle_input_available_signal, init_keyboard):
4301 * nsterm.m (ns_read_socket):
4302 * process.c (wait_reading_process_output):
4303 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4304 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4306 * xterm.c (XTread_socket):
4308 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4309 * eval.c (handling_signal): Remove. All uses removed.
4310 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4311 All uses replaced with the SYNC_INPUT version.
4312 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4314 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4317 * font.c (Ffont_shape_gstring): Remove unused local.
4319 2012-09-16 Glenn Morris <rgm@gnu.org>
4321 * Makefile.in (clean): No longer run nextstep's clean.
4323 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4325 (ns-app): Move here from ns.mk, and simplify.
4326 (clean): Simplify nextstep entry.
4327 * ns.mk: Remove file.
4329 2012-09-17 Kenichi Handa <handa@gnu.org>
4331 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4332 not covert the last few charactes.
4334 2012-09-16 Kenichi Handa <handa@gnu.org>
4336 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4337 here, but just check the validity of glyphs in the glyph-string.
4339 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4341 * window.c (Fwindow_parameter, Fset_window_parameter):
4342 Accept any window as argument (Bug#12452).
4344 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4346 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4347 to ns_term_init to avoid memory leak.
4349 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4350 explicit retain/release.
4351 (ns_term_init): Only allow one display. Initialize outerpool and
4354 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4356 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4357 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4358 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4359 the Microsoft problem in a different way, by altering ../nt/config.nt.
4361 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4376 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4377 by lisp.h. This completes removal of setjmp.h inclusion
4378 erroneously announced in the previous commit. (Bug#12446)
4380 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4383 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4384 not defined as a macro. The latter happens on MS-Windows.
4387 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4389 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4390 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4391 Some instances of '#include <setjmp.h>' removed, if the
4392 only reason for the instance was because "lisp.h" was included.
4393 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4394 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4395 and _longjmp with the new symbols. Emacs already uses _setjmp if
4396 available, so this change affects only POSIXish hosts that have
4397 sigsetjmp but not _setjmp, such as some versions of Solaris and
4398 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4399 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4400 (png_load_body) [HAVE_PNG]:
4401 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4402 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4403 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4404 since PNG requires jmp_buf. This is the only exception to the
4405 general rule that we now use sys_setjmp and sys_longjmp.
4406 This exception is OK since this code does not change the signal
4407 mask or longjmp out of a signal handler.
4409 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4411 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4412 Include "syssignal.h", for 'main_thread'.
4414 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4416 Avoid out-of-range marker position (Bug#12426).
4417 * insdel.c (replace_range, replace_range_2):
4418 Adjust markers before overlays, as suggested by comments.
4419 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4420 Remove redundant check before calling offset_intervals.
4422 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4424 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4425 current buffer (Bug#12387).
4427 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4429 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4431 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4433 Use a more backwards-compatible timer format (Bug#12430).
4434 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4435 vector element, not from the 4th, since PSECS is now at the end.
4436 (Fcurrent_idle_time): Doc fix.
4438 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4440 Function to mark objects and remove killed buffers at once.
4441 * alloc.c (discard_killed_buffers): Rename to ...
4442 (mark_discard_killed buffers) ... new name. Add marking
4443 of remaining objects. Fix comment. Adjust users.
4444 (mark_object): Do not touch frame buffer lists here.
4445 * frame.c (delete_frame): Reset frame buffer lists here.
4447 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4449 Better workaround for GNOME bug when --enable-gcc-warnings.
4450 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4451 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4452 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4454 Simplify SIGIO usage (Bug#12408).
4455 The code that dealt with SIGIO was crufty and confusing, e.g., it
4456 played tricks like "#undef SIGIO" but these tricks were not used
4457 consistently. Simplify mostly by not #undeffing standard symbols,
4458 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4459 or not as we please) rather than "defined SIGIO" (standard symbol
4460 that we probably shouldn't #undef).
4461 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4462 Modules that need it can include it.
4463 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4464 * dispextern.h (ignore_sigio): New decl.
4465 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4466 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4467 * emacs.c (shut_down_emacs):
4468 * keyboard.c (kbd_buffer_store_event_hold):
4469 Use ignore_sigio rather than invoking 'signal' directly.
4470 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4472 (FIONREAD, SIGIO): Do not #undef.
4473 (tty_read_avail_input): Use #error rather than a syntax error.
4474 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4475 for I_PIPE, used by SETUP_SLAVE_PTY.
4476 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4477 * sysdep.c (croak): Remove; no longer needed. This bit of
4478 temporary code, with Fred N. Fish's comment that it's temporary,
4479 has been in Emacs since at least 1992!
4480 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4481 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4482 * syssignal.h (croak): Remove decl.
4483 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4484 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4485 now that we're termios-only.
4486 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4487 * term.c (dissociate_if_controlling_tty): Use #error rather than
4490 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4491 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4492 to work around GNOME bug 683906.
4493 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4494 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4495 This works around GCC bug 54561.
4497 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4499 More fixes for 'volatile' and setjmp/longjmp.
4500 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4501 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4502 (png_load_body) [HAVE_PNG]:
4503 (jpeg_load_body) [HAVE_JPEG]:
4504 New function, with most of the old parent function's body.
4505 (png_load) [HAVE_PNG]:
4506 (jpeg_load) [HAVE_JPEG]:
4507 Invoke the new function, to avoid longjmp munging our locals.
4508 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4509 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4510 longjmp is passed 2, as the C standard doesn't guarantee this.
4511 Instead, store the failure code into mgr->failure_code.
4513 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4515 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4516 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4517 (syms_of_keyboard): Remove support for unread-command-char.
4519 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4521 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4522 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4523 violation. (Bug#12426)
4525 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4527 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4529 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4531 * eval.c: Add `inhibit-debugger'.
4532 (Qinhibit_debugger): New symbol.
4533 (call_debugger): Bind it instead of Qdebug_on_error.
4534 (maybe_call_debugger): Test Vinhibit_debugger.
4535 (syms_of_eval): Define inhibit-debugger.
4536 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4537 (syms_of_xdisp): Remove inhibit-debug-on-message.
4539 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4541 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4542 If a nonvolatile local variable is written before a _longjmp to
4543 the frame containing the variable, and is read after the _longjmp,
4544 the value read is indeterminate. Some local variables of type
4545 'struct handler' and 'struct catchtag' are used in this way, so
4546 mark each of their slots as volatile if the slot can be set before
4547 _longjmp and read afterwards.
4548 * lisp.h (struct handler): var and chosen_clause are now volatile.
4549 (struct catchtag): val, next, and pdlcount are now volatile.
4551 * bidi.c (bidi_push_it, bidi_pop_it):
4552 * fns.c (copy_hash_table):
4553 * image.c (define_image_type):
4554 * keyboard.c (kbd_buffer_store_event_hold):
4555 * process.c (Fprocess_send_eof):
4556 * xfaces.c (x_create_gc) [HAVE_NS]:
4557 * xgselect.c (xg_select):
4558 Prefer assignment to memcpy when either will do.
4560 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4561 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4562 time an item is removed. No need to mark this function 'inline';
4563 the compiler knows better than we do.
4565 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4567 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4568 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4569 to change_frame_size (Bug#12388).
4570 (windowDidResize:): Pass YES to updateFrameSize.
4572 * nsterm.h: Add delay parameter to updateFrameSize.
4574 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4576 Discard killed buffers from deleted window and frame objects.
4577 This reduces an amount of references to killed buffers and
4578 helps GC to reclaim them faster.
4579 * alloc.c (discard_killed_buffers): New function.
4580 (mark_object): Use it for deleted windows and frames.
4581 (mark_object): If symbol's value is set up for a killed buffer
4582 or deleted frame, restore its global binding.
4583 * data.c (swap_in_global_binding): Add GC notice.
4584 (swap_in_symval_forwarding): Use convenient set_blv_where.
4585 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4586 * window.h: ... to here.
4588 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4590 Convenient macro to check whether the buffer is live.
4591 * buffer.h (BUFFER_LIVE_P): New macro.
4592 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4593 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4595 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4597 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4598 composition cases (Bug#12364).
4600 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4601 overhang of succeeding glyphs overlapping box cursor.
4603 * w32term.c (x_draw_glyph_string): Likewise.
4605 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4607 Simplify, document, and port floating-point (Bug#12381).
4608 The porting part of this patch fixes bugs on non-IEEE platforms
4609 with frexp, ldexp, logb.
4610 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4612 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4613 support, by removing commented-out code and briefly listing the
4614 C89 functions excluded. The commented-out stuff was confusing
4615 maintenance, e.g., we thought we needed cbrt but it was commented out.
4616 (logb): Remove decl; no longer needed.
4617 (isfinite): New macro, if not already supplied.
4618 (isnan): Don't replace any existing macro.
4619 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4620 are present on all C89 platforms.
4621 (Ffrexp): Do not special-case zero, as frexp does the right thing
4623 (Flogb): Do not use logb, as it doesn't have the desired meaning
4624 on hosts that use non-base-2 floating point. Instead, stick with
4625 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4626 frexp, to avoid getting an unspecified result.
4628 * xdisp.c (Qinhibit_debug_on_message): Now static.
4630 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4632 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4633 NSBezierPath (Bug#12131).
4635 2012-09-10 Chong Yidong <cyd@gnu.org>
4637 * fns.c (Fdelq, Fdelete): Doc fix.
4639 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4641 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4642 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4644 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4646 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4647 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4650 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4652 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4653 left fringe if the window has a left margin. This avoids leaving
4654 traces of the cursor because its leftmost pixel is not drawn over.
4656 * dispnew.c (update_window_line): When the left margin area of a
4657 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4658 that screen line. (Bug#12277)
4660 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4662 Assume C89 or later for math functions (Bug#12381).
4663 This simplifies the code, and makes it a bit smaller and faster,
4664 and (most important) makes it easier to clean up signal handling
4665 since we can stop worring about floating-point exceptions in
4666 library code. That was a problem before C89, but the problem
4667 went away many years ago on all practical Emacs targets.
4668 * data.c, image.c, lread.c, print.c:
4669 Don't include <math.h>; no longer needed.
4670 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4671 might be autoconfigured, as that never happens.
4673 * doprnt.c (DBL_MAX_10_EXP):
4674 * print.c (DBL_DIG):
4675 Remove. C89 or later always defines these.
4676 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4677 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4678 (arith_error, domain_error, domain_error2):
4679 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4680 no longer needed -- we simply return what C returns. All uses removed.
4681 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4683 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4684 Remove. All uses expanded, as these macros are no longer used
4685 more than once and are now more trouble than they're worth.
4686 (Ftan): Use tan, not sin / cos.
4687 (Flogb): Assume C89 frexp.
4688 (fmod_float): Assume C89 fmod.
4689 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4690 (init_floatfns): Remove. All uses removed.
4692 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4694 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4695 compositeToPoint for OSX < 10.6 (Bug#12390).
4697 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4699 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4700 This produces more-accurate results.
4702 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4704 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4705 changes (Bug#12088).
4707 2012-09-08 Chong Yidong <cyd@gnu.org>
4709 * syntax.c (Fstring_to_syntax): Doc fix.
4711 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4713 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4714 in the internal border.
4715 (x_set_window_size): Remove static variables and their usage.
4716 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4717 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4718 Remove fringe/internal border adjustment (Bug#11052).
4719 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4720 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4721 (ns_fix_rect_ibw): Remove.
4722 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4723 (ns_dumpglyphs_box_or_relief): Ditto.
4724 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4726 (ns_dumpglyphs_image): Ditto.
4727 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4729 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4730 their usage. Add fringe_extended_p and its use as in other terms.
4731 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4732 scroll bar was removed.
4733 (updateFrameSize): New function.
4734 (windowDidResize): Move code to updateFrameSize and call it.
4736 * nsterm.h (EmacsView): Add updateFrameSize.
4738 2012-09-07 Chong Yidong <cyd@gnu.org>
4740 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4742 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4744 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4746 More signal-handler cleanup (Bug#12327).
4747 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4748 Problem introduced when merging patches. Noted by Eli Zaretskii in
4749 <http://bugs.gnu.org/12327#67>.
4750 * floatfns.c: Comment fix.
4751 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4752 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4753 and anyway the declaration is harmless even if SIGDANGER is not defined.
4754 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4755 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4756 source files not surprisingly expected syssignal.h to define, or
4757 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4758 Include <sys/ioctl.h>, for FIONREAD.
4759 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4760 This eliminates a problem whereby other files mysteriously had
4761 to include "syssignal.h" before including "systty.h" if they
4762 wanted to use "#ifdef SIGIO".
4764 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4766 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4768 * w32.c (sigemptyset): Empty the set.
4769 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4771 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4773 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4775 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4776 (mark_object): Likewise for frame objects.
4778 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4780 * syssignal.h (handle_on_main_thread): Always declare,
4781 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4782 This ports to platforms without HAVE_PTHREAD.
4784 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4786 Signal-handler cleanup (Bug#12327).
4787 Emacs's signal handlers were written in the old 4.2BSD style with
4788 sigblock and sigmask and so forth, and this led to some
4789 inefficiencies and confusion. Rewrite these to use
4790 pthread_sigmask etc. without copying signal sets around. Also,
4791 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4792 'signal', and instead use functions that do not attempt to take
4793 over the system name space. This patch causes Emacs's text
4794 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4795 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4796 Do not include <signal.h> or "syssignal.h", as these
4797 modules do not use signals.
4798 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4799 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4800 Do not include <signal.h>, as "syssignal.h" does that for us now.
4801 * atimer.c (sigmask_atimers): New function.
4802 (block_atimers, unblock_atimers): New functions,
4803 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4805 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4806 no longer needed here.
4807 * emacs.c (main): Inspect existing signal handler with sigaction,
4808 so that there's no need to block and unblock SIGHUP.
4809 * sysdep.c (struct save_signal): New member 'action', replacing
4810 old member 'handler'.
4811 (save_signal_handlers, restore_signal_handlers):
4812 Use sigaction instead of 'signal' to save and restore.
4813 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4814 New function. All users of 'signal' modified to use set_sighandler
4815 if they're writeonly, and to use sys_signal if they're read+write.
4816 (emacs_sigaction_init, forwarded_signal): New functions.
4817 (sys_signal): Remove. All uses replaced by calls to sigaction
4818 and emacs_sigaction_init, or by direct calls to 'signal'.
4819 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4820 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4821 all uses replaced by pthread_sigmask etc. calls.
4822 * syssignal.h: Include <signal.h>.
4823 (emacs_sigaction_init, forwarded_signal): New decls.
4824 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4825 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4826 (sigmask, sys_sigmask): Remove; no longer needed.
4827 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4828 (sigblock, sigunblock, sigfree):
4829 (sigsetmask) [!defined sigsetmask]:
4830 Remove. All uses replaced by pthread_sigmask.
4831 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4832 no longer need to be replaced, and its typical old uses
4833 are now done via emacs_sigaction_init and sigaction.
4834 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4835 (sys_sigdel): Remove; unused.
4836 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4838 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4840 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4841 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4843 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4845 Explicitly mark buffer_defaults and buffer_local_symbols.
4846 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4847 mark_local_symbols here.
4848 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4849 since special buffers aren't marked here any more.
4850 (allocate_buffer): Chain new buffer with all_buffers here...
4851 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4853 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4854 (syms_of_buffer): Remove staticpro of the above.
4855 (init_buffer_once): Set names for buffer_defaults and
4856 buffer_local_symbols.
4858 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4860 Use bool for booleans in font-related modules.
4861 * font.c (font_intern_prop, font_style_to_value)
4862 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4863 (generate_otf_features, font_check_otf_features, font_check_otf)
4864 (font_match_p, font_list_entities, font_at):
4865 * fontset.c (fontset_id_valid_p, reorder_font_vector
4866 (fontset_find_font, Fset_fontset_font)
4867 (face_suitable_for_char_p) [0]:
4868 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4869 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4870 (m17n_flt_initialized, ftfont_shape_by_flt):
4871 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4872 * nsfont.m (nsfont_draw):
4873 * w32font.c (w32font_draw):
4874 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4875 Use bool for booleans.
4876 * font.h: Adjust to above API changes.
4877 (struct font, struct font_driver, struct font_driver_list):
4878 Use bool for booleans.
4879 (struct font): Remove useless member encoding_type.
4881 * fontset.c, xftfont.c: Omit unnecessary static decls.
4883 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4885 * alloc.c (mark_object): Revert window marking code
4886 since it's unsafe for the Fset_window_configuration.
4888 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4890 Fix race conditions with signal handlers and errno (Bug#12327).
4891 Be more systematic about preserving errno whenever a signal
4892 handler returns, even if it's not in the main thread. Do this by
4893 renaming signal handlers to distinguish between signal delivery
4894 and signal handling. All uses changed.
4895 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4896 * data.c (deliver_arith_signal): Rename from arith_error.
4897 * dispnew.c (deliver_window_change_signal): Rename from
4898 window_change_signal.
4899 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4900 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4901 * keyboard.c (deliver_input_available_signal): Rename from
4902 input_available_signal.
4903 (deliver_user_signal): Rename from handle_user_signal.
4904 (deliver_interrupt_signal): Rename from interrupt_signal.
4905 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4906 (deliver_child_signal): Rename from sigchld_handler.
4907 * atimer.c (handle_alarm_signal):
4908 * data.c (handle_arith_signal):
4909 * dispnew.c (handle_window_change_signal):
4910 * emacs.c (handle_fatal_signal, handle_danger_signal):
4911 * keyboard.c (handle_input_available_signal):
4912 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4913 * process.c (handle_pipe_signal, handle_child_signal):
4914 New functions, with the actual signal-handling code taken from the
4915 original respective signal handlers, sans the sporadic attempts to
4916 preserve errno, since that's now done by handle_on_main_thread.
4917 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4918 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4919 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4921 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4922 Move initialization of main_thread to sysdep.c's init_signals.
4923 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4924 our usage, and simplifies the mainline code.
4925 (record_child_status_change): New static function, as a helper
4926 for handle_child_signal, and with most of the old child handler's
4928 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4929 (handle_child_signal): Use the above.
4930 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4931 Moved here from emacs.c.
4932 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4933 code moved here from emacs.c's main function.
4934 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4935 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4936 This lets callers save and restore errno properly.
4938 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4940 Remove redundant or unused things here and there.
4941 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4942 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4943 * editfns.c (Fcompare_buffer_substrings): Likewise.
4944 * frame.h (struct terminal, struct font_driver_list):
4945 Remove redundant declarations.
4946 * window.h (Qleft, Qright): Likewise.
4948 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4950 Do not mark objects from deleted buffers, windows and frames.
4951 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4952 (mark_object): Likewise for windows and frames.
4954 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4956 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4957 buffer_defaults and buffer_local_symbols as valid objects.
4958 Return special value to denote them.
4960 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4962 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4963 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4964 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4965 (file_name_absolute_p, Fsubstitute_in_file_name):
4966 (check_executable, check_writable, Ffile_accessible_directory_p)
4967 (Fset_file_selinux_context, Fdefault_file_modes)
4968 (Finsert_file_contents, choose_write_coding_system)
4969 (Fwrite_region, build_annotations, a_write, e_write)
4971 * filelock.c (boot_time_initialized, get_boot_time)
4972 (get_boot_time_1, lock_file_1, within_one_second):
4973 * floatfns.c (in_float):
4974 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4975 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4976 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4977 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4978 * window.c (compare_window_configurations):
4979 Use bool for booleans.
4980 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4981 (Fdefault_file_modes): Now mode_t, not int, for modes.
4982 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4983 (internal_delete_file): Now returns void, not a (boolean) int,
4984 since nobody was looking at the return value.
4985 * lisp.h, window.h: Adjust to above API changes.
4987 * xdisp.c (set_message): Simplify and reindent last change.
4989 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4991 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4993 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4995 * eval.c (call_debugger): Make the function non-static so that we
4996 can call it from set_message.
4998 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4999 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5001 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5003 Give more-useful info on a fatal error (Bug#12328).
5004 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5005 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5006 of doing the work ourselves.
5007 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5008 do most of the work.
5009 (fatal_error_backtrace): New function, taken from the guts
5010 of the old fatal_error_signal, but with a new option to output
5012 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5013 info about the signal than just its number.
5014 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5015 * sysdep.c: Include <execinfo.h>
5016 (emacs_backtrace): New function, taken partly from the previous
5017 code of the 'die' function.
5018 (emacs_abort): Call fatal_error_backtrace rather than abort.
5020 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5022 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5023 eager (load-time) macro-expansion.
5024 * lisp.mk (lisp): Add macroexp.
5026 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5028 Simplify redefinition of 'abort' (Bug#12316).
5029 Do not try to redefine the 'abort' function. Instead, redo
5030 the code so that it calls 'emacs_abort' rather than 'abort'.
5031 This removes the need for the NO_ABORT configure-time macro
5032 and makes it easier to change the abort code to do a backtrace.
5033 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5034 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5035 Remove; sysdep.c's emacs_abort now takes its place.
5036 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5037 'abort' changed to use 'emacs_abort'.
5038 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5039 (abort) [!defined abort]: Rename to ...
5040 (emacs_abort): ... new name.
5041 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5042 the place of the old 'abort' in emacs.c.
5043 * w32.c, w32fns.c (abort): Do not #undef.
5044 * w32.c (emacs_abort): Rename from w32_abort.
5046 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5048 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5049 offsets[j].dv, since the y axis of the screen coordinates points
5050 down, while the y axis of the font definition coordinates points
5051 up. This fixes display of Arabic diacritics such as KASRA and
5052 KASRATAN. (Bug#11860)
5054 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5056 Be more systematic about _setjmp vs setjmp.
5057 * alloc.c (test_setjmp, mark_stack):
5058 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5059 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5060 (png_load, my_error_exit, jpeg_load):
5061 * process.c (send_process_trap, send_process):
5062 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5063 The underscored versions are up to 30x faster on some hosts.
5064 Formerly, the code used setjmp+longjmp sometimes and
5065 _setjmp+_longjmp at other times, with no particular reason to
5066 prefer setjmp+longjmp.
5068 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5070 Fix minor problem found by static checking.

5097 EXCLUDE_SUBRS_P. All callers changed.
5098 * dispextern.h, lisp.h: Reflect above API changes.
5099 * firstfile.c (dummy): Use the address of 'main', whose signature
5100 won't change, instead of the address of 'initialize', whose
5101 signature just changed from int to bool.
5102 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5103 * msdos.c (fatal_error_in_progress): ... from here.
5104 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5106 (redisplay_internal, unwind_redisplay): Simply clear
5107 REDISPLAYING_P when unwinding, instead of saving its previous,
5108 always-false value and then restoring it.
5110 Clean up some extern decls.
5111 Mostly, this hoists extern decls out of .c files and into .h files.
5112 That way, we're more likely to catch errors if the interfaces change.
5113 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5114 declare xg_mark_data.
5115 * dispextern.h (x_frame_parm_handlers):

5135 Remove now-redundant extern decls.
5136 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5137 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5139 * xfaces.c: Remove unnecessary static decls.
5140 * xterm.c (updating_frame): Remove decl of nonexistent object.
5142 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5143 when building globals.h, as the objects that are not built on
5144 this host are not needed to compile C files on this host.
5146 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5148 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5196 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5198 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5199 more than one grapheme cluster passed to the shaper: compute the
5200 offset adjustment values separately for each cluster. (Bug#11860)
5202 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5203 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5204 about implicit conversions from integer to pointer.
5206 2012-09-01 Daniel Colascione <dancol@dancol.org>
5208 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5209 system used too early.
5211 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

5262 window system declarations.
5264 * frame.h: Move common functions here: set_frame_menubar,
5265 x_set_window_size, x_sync, x_get_focus_frame,
5266 x_set_mouse_position, x_set_mouse_pixel_position,
5267 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5294 * lisp.h (mark_ttys): Remove prototype.
5295 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

5297 the frames which are reachable from Vframe_list.
5298 * term.c (mark_ttys): Remove.
5299 (init_tty): Safely initialize 'top_frame' slot with Qnil.

5328 * lread.c (init_lread): For out-of-tree builds, only add the
5329 source directory's site-lisp dir to the load-path if it exists,
5330 consistent with in-tree builds. (Bug#12302)

5351 Handle click on close button as quit.
5353 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5354 Add window_closed and button_values. Add void as return value for
5355 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5356 Add process_dialog as new member.
5358 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5360 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5490 (code_convert_string, code_convert_string_norecord)
5491 (Fset_coding_system_priority):
5492 * fileio.c (Finsert_file_contents):
5493 Use bool for booleans.
5494 * coding.h, lisp.h: Reflect above API changes.
5495 * coding.c: Remove unnecessary static function decls.
5496 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5497 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5498 not a boolean 'int', since callers never look at the return value.
5499 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5500 * coding.h (decoding_buffer_size, encoding_buffer_size)
5501 (emacs_mule_string_char): Remove unused extern decls.
5502 (struct iso_2022_spec, struct coding_system):
5503 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5504 (struct emacs_mule_spec): Remove unused field 'full_support'.
5505 All initializations removed.
5506 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5508 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5510 Fix spare memory change (Bug#12286).
5511 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5512 (valid_lisp_object_p): Likewise.
5514 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5516 * window.c (Fset_window_configuration): Record any window's old
5517 buffer if it's replaced (see Bug#8789). If the new current
5518 buffer doesn't appear in the selected window, go to its old
5521 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5523 Special MEM_TYPE_SPARE to denote reserved memory.
5524 * alloc.c (enum mem_type): New memory type.
5525 (refill_memory_reserve): Use new type for spare memory.
5526 This prevents live_cons_p and live_string_p from incorrect
5527 detection of uninitialized objects from spare memory as live.
5529 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5532 * Makefile.in (.PHONY): versioclean -> versionclean.
5534 Remove unused external symbols.
5535 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5536 * window.c (Qwindow_valid_p, decode_valid_window):
5537 Now static, not extern.
5538 * data.c (Qinterval): Remove; unused.
5539 (syms_of_data): Do not define 'interval'.
5540 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5541 * window.h (decode_valid_window):
5544 * character.c, charset.c, chartab.c: Use bool for booleans.
5545 * character.c (lisp_string_width, string_count_byte8)
5546 (string_escape_byte8):
5547 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5548 (load_charset_map_from_file, map_charset_chars)

5550 (Fdeclare_equiv_charset, find_charsets_in_text)
5551 (Ffind_charset_region, char_charset, Fiso_charset):

5553 (sub_char_table_set, sub_char_table_set_range)
5554 (char_table_set_range, optimize_sub_char_table)
5555 (map_sub_char_table):
5556 Use bool for boolean.
5557 * character.c (str_to_unibyte): Omit last boolean argument; it was
5558 always 0. All callers changed.
5559 * character.h, charset.h: Adjust to match previous changes.
5560 * character.h (char_printable_p): Remove decl of nonexistent function.
5561 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5562 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5563 are all boolean, so make them single-bit bitfields.
5565 * lisp.h (ASET): Remove attempt to detect side effects.
5566 It was meant to be temporary and it often doesn't work,
5567 because when IDX has side effects the behavior of IDX==IDX
5568 is undefined. See Stefan Monnier in
5569 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5571 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5573 * lisp.h (functionp): New function (extracted from Ffunctionp).
5574 (FUNCTIONP): Use it.
5575 * eval.c (Ffunctionp): Use it.
5577 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5579 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5580 as that's faster and simpler than static storage. Don't bother
5581 with the g_main_context_query overhead if g_main_context_pending
5582 says no events are pending.
5583 (gfds, gfds_size): Remove these static vars.
5584 (xgselect_initialize): Remove; no longer needed.
5585 All uses and decls removed.
5587 * emacs.c (fatal_error_signal_hook): Remove.
5588 All uses removed. This leftover from old code was always 0.
5590 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5591 * casefiddle.c (casify_object, casify_region):
5592 * casetab.c (set_case_table):
5593 * category.c, category.h (word_boundary_p):
5594 * category.h (CHAR_HAS_CATEGORY):
5595 Use bool for booleans, instead of int.
5597 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5599 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5601 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5603 On assertion failure, print backtrace if available.
5604 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5605 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5606 * Makefile.in (LIB_EXECINFO): New macro.
5609 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5610 * bytecode.c (exec_byte_code):
5611 * callint.c (check_mark, Fcall_interactively):
5612 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5613 (getenv_internal, sync_process_alive, call_process_exited):
5614 * lisp.h (USE_SAFE_ALLOCA):
5615 Use bool for booleans, instead of int.
5616 * lisp.h, process.h: Adjust prototypes to match above changes.
5617 * callint.c (Fcall_interactively): Don't assume the mark's
5618 offset fits in 'int'.
5620 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5622 * buffer.c, buffer.h: Use bool for boolean.
5623 * buffer.c (reset_buffer_local_variables)
5624 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5625 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5626 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5627 (overlay_touches_p, overlay_strings, Foverlay_put)
5628 (report_overlay_modification, call_overlay_mod_hooks):
5629 (mmap_enlarge, mmap_set_vars):
5630 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5631 Use bool for booleans, instead of int.
5632 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5633 since the 1-or-0 return value is always ignored anyway.
5634 (mmap_initialized_p):
5635 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5636 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5638 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5640 * bidi.c: Use bool for boolean.
5641 This is a bit more readable, and makes the text segment of bidi.o
5642 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5643 Presumably it's faster too.
5644 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5646 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5647 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5648 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5649 (bidi_explicit_dir_char, bidi_level_of_next_char)
5650 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5651 Use bool for booleans, instead of int.
5652 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5653 (bidi_unshelve_cache): Adjust decls to match code.
5655 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5657 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5660 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5662 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5663 * atimer.h: Include <stdbool.h>.
5665 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5667 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5668 compile time tests instead of run time tests on systems that do
5670 (FRAME_MAC_P): Remove leftover from deleted code.
5671 * frame.c (syms_of_frame): Remove leftover from deleted code.
5673 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5675 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5677 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5679 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5680 Otherwise, the compiler complains about (A?B:C) where B is void
5681 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5682 (fontset_add): Return void, for FONTSET_ADD.
5684 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5686 * alloc.c: Use bool for booleans.
5687 (gc_in_progress, abort_on_gc)
5688 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5689 (dont_register_blocks) [GC_MALLOC_CHECK]:
5690 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5691 (check_string_bytes, make_specified_string, memory_full)
5692 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5693 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5694 (mark_stack, valid_pointer_p, make_pure_string)
5695 (Fgarbage_collect, survives_gc_p, gc_sweep):
5696 Use bool for booleans, instead of int.
5697 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5698 Remove unused local.
5699 * alloc.c (PURE_POINTER_P):
5700 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5701 * editfns.c (Fformat):
5702 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5704 * fns.c (sweep_weak_table):
5705 * lisp.h (suppress_checking, push_message, survives_gc_p)
5706 (make_pure_string, gc_in_progress, abort_on_gc):
5707 * lread.c (readchar, read1):
5708 * print.c (Fprin1_to_string):
5709 * xdisp.c (push_message):
5710 Use bool for booleans affected directly or indirectly by
5713 Make recently-introduced setters macros.
5714 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5715 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5716 (set_fontset_default, set_fontset_fallback): Rename from their
5717 upper-case counterparts, and make them functions rather than macros.
5718 This is more consistent with the other recently-introduced setters.
5719 These don't need to be inline, since they're local.
5721 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5723 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5724 the loop (Bug#12247).
5726 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5728 * lisp.h (vcopy): Use memcpy rather than our own loop.
5729 This fixes a performance regression introduced by the recent
5730 addition of vcopy. This means 'vcopy' will need to be modified
5731 for a copying collector, but that's OK. Also, tighten the
5732 checking in the assertion.
5734 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5736 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5737 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5738 non-base glyph for the width of the base character, according to
5739 what x_draw_composite_glyph_string_foreground expects.
5740 Generate WADJUST value according to composition_gstring_width's
5741 expectations, to produce correct width of the composed character.
5742 Reverse the sign of the DU offset produced by ScriptPlace.
5744 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5746 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5748 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5750 Avoid direct writes to contents member of struct Lisp_Vector.
5751 * lisp.h (vcopy): New function to copy data into vector.
5752 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5753 * fns.c (Ffillarray): Use ASET.
5754 * keyboard.c (timer_check_2): Use AREF and ASET.
5755 (append_tool_bar_item, Frecent_keys): Use vcopy.
5756 * lread.c (read_vector): Use ASET.
5757 * msdos.c (Frecent_doskeys): Use vcopy.
5758 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5759 (Finternal_merge_in_global_face): Use ASET and vcopy.
5760 * xfont.c (xfont_list_pattern): Likewise.
5762 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5764 * window.c (Fwindow_point): For the selected window always return
5765 the position of its buffer's point.
5766 (Fset_window_point): For the selected window always go in its
5767 buffer to the specified position.
5769 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5771 Setter macros for fontsets.
5772 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5773 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5774 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5777 2012-08-20 Glenn Morris <rgm@gnu.org>
5779 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5780 Don't assume that `ln -f' works.
5782 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5784 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5785 and later about non-assignments with no effect. See discussion at
5786 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5789 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5791 Inline setter functions for Lisp_Objects slots of struct specbinding.
5792 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5795 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5797 * window.c (select_window): Always make selected window's buffer
5800 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5802 Use AREF and ASET for docstrings of category tables.
5803 * category.h (CATEGORY_DOCSTRING): Use AREF.
5804 (SET_CATEGORY_DOCSTRING): Use ASET.
5805 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5807 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5809 Inline setter functions for hash table members.
5810 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5811 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5812 (set_hash_key_and_value, set_hash_index, set_hash_next)
5813 (set_hash_hash): New functions.
5814 * charset.c, fns.c: Adjust users.
5816 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5818 Inline getter and setter functions for per-buffer values.
5819 * buffer.h (per_buffer_default, set_per_buffer_default)
5820 (per_buffer_value, set_per_buffer_value): New functions.
5821 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5822 * buffer.c, data.c: Adjust users.
5824 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5826 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5828 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5830 Rely on <config.h> + <unistd.h> to declare 'environ',
5831 as gnulib does this if the system doesn't.
5832 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5833 Remove declaration. MS-Windows declares it on stdlib.h which is
5834 included by conf_post.h.
5835 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5836 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5837 * vm-limit.c: Include <unistd.h>, for 'environ'.
5839 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5840 (start_of_data): Remove decl; mem-limits.h provides it.
5842 * xdisp.c (handle_invisible_prop): Make it a bit faster
5843 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5845 2012-08-19 Chong Yidong <cyd@gnu.org>
5847 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5850 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5852 * .gdbinit: Use call instead of set when calling a function in the
5855 * data.c (set_internal): Don't use set_blv_found.
5856 (Fkill_local_variable): Likewise.
5858 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5860 * nsfont.m (ns_ascii_average_width): Ensure the string
5861 ascii_printable is initialized with a null-terminated character
5862 array. Otherwise, it can contain undesired extra characters.
5864 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5866 port new setting code to Sun C 5.8 2005/10/13
5867 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5868 Return void, not Lisp_Object. Otherwise, the compiler
5869 complains about (A?B:C) where B is void and C is Lisp_Object
5870 when compiling CHAR_TABLE_SET, due to the recent change to
5871 the API of sub_char_table_set_contents.
5873 2012-08-18 Chong Yidong <cyd@gnu.org>
5875 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5876 for the string case (Bug#3874).
5878 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5880 * buffer.h (BSET): Remove (Bug#12215).
5881 Replace all uses with calls to new setter functions.

5909 * category.c (bset_category_table):
5910 * syntax.c (bset_syntax_table):
5911 New setter functions.
5913 * process.h (PSET): Remove (Bug#12215).

6812 Fix macroexp crash on Windows with debugging (Bug#12118).
6813 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6814 checking subscripts; problem introduced with the recent
6815 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6816 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6817 since it's used in non-static inline functions now.
6819 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

6846 (INLINE_HEADER_END): New macros.
6847 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6873 it easier to think about future improvements. See
6874 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6875 * charset.h (set_charset_attr): New function.

7256 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7257 (w32_kbd_patch_key, key_event): Use the codepage returned by
7258 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7259 (key_event): use uChar.UnicodeChar only if
7260 w32_console_unicode_input is non-zero.

7290 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7291 enumeration constants, as PURE and HEAP are too general, and clash
7292 with other headers and sources, such as gmalloc.c and the
7293 MS-Windows system headers. All users changed.
7295 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7297 Revert last save_excursion_save and save_excursion_restore changes.
7298 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7308 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7310 Improve GDB symbol export (Bug#12036).
7311 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7312 arms of an 'if', not using conditional expressions; otherwise GDB
7313 complains about the types in the unevaluated arm when the argument
7314 is an integer literal.
7315 (xgetint): Simplify expression.
7316 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7317 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7318 Zaretskii in <http://bugs.gnu.org/12036#13>.
7319 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7320 needed now that we have gdb_make_enums_visible.
7321 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7322 (enum enum_USE_LSB_TAG):
7323 New enum types, packaging up enums that need to be exported to GDB.

7342 * xfns.c (syms_of_xfns): Likewise.
7344 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

7347 * lisp.h (struct Lisp_Excursion): New data type.
7348 (PVEC_EXCURSION): New pseudovector type.
7349 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7350 to deal with it. Adjust comments.

7365 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7366 emacs.c, as this is a more-suitable home. Had this been done earlier
7367 the fix for 12036 would have avoided some of the problems noted in
7368 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7369 would have been more obvious.
7370 * emacs.c: Do not include <verify.h>; no longer needed.
7371 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7372 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7373 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7374 Remove; now done in lisp.h.

7377 (DATA_SEG_BITS): Use it.
7378 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7379 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7380 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7381 not be usable in #if. This simplifies things.
7383 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7385 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7387 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7389 Simplify export of symbols to GDB (Bug#12036).
7390 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7391 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7392 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7393 Adjust to changes in lisp.h and emacs.c, by using
7394 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7395 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7396 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7397 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7398 instead of gdb_valbits.
7399 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7400 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7401 instead of gdb_array_mark_flag.
7402 (xboolvector): Get size from $->size, not $->header.size.
7403 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7404 (xreload, hook-run, hookpost-run): Remove.
7405 * emacs.c: Include <verify.h>.
7406 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7407 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7409 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7410 (gdb_USE_LSB_TAG): New enum constants.
7411 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7412 Also define these as enum constants, so they're visible to GDB.
7413 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7414 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7415 as constants, so they're visible to GDB.
7416 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

7418 Now enum constants, not macros, so they're visible to GDB.
7419 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7420 more convenient now. All uses changed.
7421 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7422 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7424 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7431 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7432 add argument, tune behavior, and adjust all callers.
7434 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7436 Use typedef for EMACS_INT, EMACS_UINT.
7437 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7438 than macros. This simplifies debugging in the usual case, since
7439 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7440 and it allows expressions involving EMACS_INT casts.
7441 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7443 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7453 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7455 Adjust buffer text indirection counters at the end of Fkill_buffer.
7456 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7457 buffer is definitely dead. This should really fix an issue reported
7458 by Christoph Scholtes again. (Bug#12007).
7459 (init_buffer_once): Initialize indirection counters of
7460 buffer_defaults and buffer_local_symbols (for sanity and safety).
7462 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7464 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7465 and continuation glyphs on tooltip frames, leave them at zero.

7468 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7470 Simplify copy_overlay.
7471 * buffer.c (copy_overlay): Simplify. Use build_marker.

7493 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7495 Swap buffer text indirection counters in Fbuffer_swap_text.
7496 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7497 This avoids crash reported by Christoph Scholtes at
7498 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7500 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7502 * nsmenu.m (Popdown_data): New struct.
7503 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7505 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7506 (initWithContentRect): Make imgView and contentView non-static
7507 and autorelease them. Also autorelease img and matrix (Bug#12005).
7508 (dealloc): Remove (Bug#12005).
7510 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7512 Adjust consing_since_gc when objects are explicitly freed.

7525 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7527 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7528 as it's limited by the amount of memory, not by INT_MAX.
7530 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7532 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7533 in special-event-map. See the discussion at

7592 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
7593 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
7594 Adjust users accordingly.
7595 * font.h (font_open_by_name): Adjust prototype.

7614 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7615 'for_each_per_buffer_object_at'.
7616 All uses changed. It's better to use upper-case for macros that
7617 cannot be implemented as functions, to give the reader a clue
7618 that they're special.
7620 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
7622 * alloc.c (Fgarbage_collect): Tweak docstring.

7663 * intervals.c (merge_interval_right, merge_interval_left):
7664 Do not zero out this interval if it is absorbed by its children,

7668 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
7670 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
7671 when invoking (make-bool-vector N t) and N is a positive

8141 2012-07-11 Glenn Morris <rgm@gnu.org>
8143 * s/gnu-linux.h, s/sol2-6.h: No longer define POSIX,
8144 unused since 2011-01-17 change to systty.h.

8184 2012-07-11 Glenn Morris <rgm@gnu.org>
8186 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8187 since nothing has defined it on these platforms.
8189 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
8190 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

8201 2012-07-11 John Wiegley <johnw@newartisans.com>
8203 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8204 function attribute, so we only use it if it exists in the
8207 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8209 Avoid call to strlen in fast_c_string_match_ignore_case.

8211 length argument. Adjust users accordingly.
8212 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
8214 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

8256 * s/aix4-2.h (unix): Remove; no longer needed.
8258 EMACS_TIME simplification (Bug#11875).
8259 This replaces macros (which typically do not work in GDB)
8260 with functions, typedefs and enums, making the code easier to debug.
8261 The functional style also makes code easier to read and maintain.
8262 * systime.h: Include <sys/time.h> on all hosts, not just if
8263 WINDOWSNT, since 'struct timeval' is needed in general.
8264 (EMACS_TIME): Now a typedef, not a macro.
8265 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8267 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8271 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8272 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8273 which are not functions. All uses rewritten to use:
8274 (make_emacs_time): New function.
8275 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8276 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8277 not functions. All uses rewritten to use the following, respectively:
8278 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8279 (add_emacs_time, sub_emacs_time): New functions.
8280 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8281 * fileio.c (Fcopy_file):
8282 * xterm.c (XTflash): Get the current time closer to when it's used.
8283 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8291 * gtkutil.c (get_utf8_string):
8293 * nsmenu.m (ns_update_menubar):
8294 * regex.c (regerror):
8295 Prefer memcpy to strncpy and strncat when either will do.
8296 * fileio.c (Fsubstitute_in_file_name):
8297 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8298 (menu_separator_name_p):
8299 * nsmenu.m (ns_update_menubar):
8300 Prefer memcmp to strncmp when either will do.
8301 * nsterm.m: Include <ftoastr.h>.
8303 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8304 Prefer snprintf to strncpy.
8305 * nsterm.m (ns_term_init):
8306 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8307 * nsterm.m (ns_term_init):
8308 Avoid the need for strncpy, by using build_string or
8309 make_unibyte_string directly. Use dtoastr, not snprintf.
8310 * process.c (Fmake_network_process): Diagnose service names that
8311 are too long, rather than silently truncating them or creating
8312 non-null-terminated names.
8313 (Fnetwork_interface_info): Likewise, for interface names.
8314 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8315 Prefer sprintf to strncat.
8316 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8317 Prefer vsnprintf to vsprintf + strncpy.
8319 2012-07-10 Glenn Morris <rgm@gnu.org>
8321 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8322 Clarify fallback case.
8324 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8326 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8327 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8328 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8329 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8330 where argument type is known to be a Lisp_Cons.
8332 2012-07-10 Tom Tromey <tromey@redhat.com>
8334 * bytecode.c (BYTE_CODE_THREADED): New macro.
8335 (BYTE_CODES): New macro. Replaces all old byte-code defines.

8342 Optimize pure C strings initialization.
8343 * lisp.h (make_pure_string): Fix prototype.
8344 (build_pure_c_string): New function, defined as static inline. This
8345 provides a better opportunity to optimize away calls to strlen when
8346 the function is called with compile-time constant argument.
8347 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8348 argument, adjust users accordingly. Use build_pure_c_string where
8350 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8351 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8352 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8354 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8356 Avoid calls to strlen in miscellaneous functions.
8357 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8358 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8359 * lread.c (openp): Likewise.
8361 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8363 Avoid calls to strlen in path processing functions.
8364 * fileio.c (file_name_as_directory): Add comment. Change to add
8365 srclen argument and return the length of result. Adjust users
8367 (directory_file_name): Fix comment. Change to add srclen argument,
8368 swap 1st and 2nd arguments to obey the common convention.
8369 Adjust users accordingly.
8370 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8372 2012-07-10 Glenn Morris <rgm@gnu.org>
8374 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8377 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8378 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8379 * s/gnu.h (DATA_START): Move definitions to configure.
8381 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8382 We include usg5-4-common.h, which defines them both.
8384 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8385 O_RDONLY already includes it).
8387 Stop ns builds setting the EMACSLOADPATH environment variable.
8388 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8389 Now it does not set EMACSLOADPATH, just returns the load-path string.
8390 * nsterm.h: Update accordingly.
8391 * lread.c [HAVE_NS]: Include nsterm.h.
8392 (init_lread) [HAVE_NS]: Use ns_load_path.
8393 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8395 2012-07-09 Glenn Morris <rgm@gnu.org>
8397 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8398 since the included bsd-common.h does so.
8400 Stop ns builds setting the EMACSPATH environment variable.
8401 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8402 (ns_init_paths): Do not set EMACSPATH.
8403 * nsterm.h (ns_exec_path): Add it.
8404 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8407 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8409 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8411 * process.c (wait_reading_process_output): 'waitchannels' was unset
8412 when read_kbd || !NILP (wait_for_cell); fix this.
8414 Add GCC-style 'const' attribute to functions that can use it.
8415 * character.h (char_resolve_modifier_mask):
8416 * keyboard.h (make_ctrl_char):
8417 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8418 (init_character_once, next_almost_prime, init_fns, init_image)
8419 (flush_pending_output, init_sound):
8420 * mem-limits.h (start_of_data):
8421 * menu.h (finish_menu_items):
8422 Add ATTRIBUTE_CONST.

8424 Declare the dummy function with ATTRIBUTE_CONST.
8425 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8426 Add decls with ATTRIBUTE_CONST.
8428 Minor improvements to make_formatted_string.
8429 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8430 where int is good enough, as vsprintf returns an int.
8431 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8433 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8435 Use make_formatted_string to avoid double length calculation.
8436 * lisp.h (make_formatted_string): New prototype.
8437 * alloc.c (make_formatted_string): New function.
8438 * buffer.c (Fgenerate_new_buffer_name): Use it.
8439 * dbusbind.c (syms_of_dbusbind): Likewise.
8440 * editfns.c (Fcurrent_time_zone): Likewise.
8441 * filelock.c (get_boot_time): Likewise.
8442 * frame.c (make_terminal_frame, set_term_frame_name)
8443 (x_report_frame_params): Likewise.
8444 * image.c (gs_load): Likewise.
8445 * minibuf.c (get_minibuffer): Likewise.
8446 * msdos.c (dos_set_window_size): Likewise.
8447 * process.c (make_process): Likewise.
8448 * xdisp.c (ensure_echo_area_buffers): Likewise.

8451 2012-07-09 Glenn Morris <rgm@gnu.org>
8453 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.

8460 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8462 Move marker debugging code under MARKER_DEBUG.
8463 * marker.c (MARKER_DEBUG): Move marker debugging code under
8464 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8465 for bootstrap with --enable-checking (~3x slowdown reported
8466 by Juanma Barranquero <lekktu@gmail.com>).
8467 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8469 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8471 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8472 See <http://bugs.gnu.org/11825#29>.
8474 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8476 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8477 has no font, use the frame's font. (Bug#11813)
8478 (display_line): Add commentary about displaying truncation glyphs
8480 (produce_special_glyphs): Move here from term.c.
8482 * term.c (produce_special_glyphs): Move to xdisp.c.
8484 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8487 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8489 * xdisp.c (display_line): Avoid warning about implicit declaration
8492 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8494 * lisp.h: Remove empty conditional.
8496 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8498 * lread.c (load_path_check): Now static.
8500 Fix some minor --with-ns problems found by static checking.
8501 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8502 (x_set_font) [!HAVE_X_WINDOWS]:
8503 * image.c (xpm_load_image) [HAVE_NS]:
8504 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8505 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8506 Remove unused local.
8507 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8508 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8509 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8510 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8511 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8512 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8513 Fix pointer signedness problem.
8514 * xfaces.c (FRAME_X_FONT_TABLE):
8515 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8517 2012-07-07 Glenn Morris <rgm@gnu.org>
8519 * lread.c (load_path_check): New function, split from init_lread.
8520 (init_lread): Reorganize. Motivation:
8521 If EMACSLOADPATH is set, check/warn about that rather than the
8522 defaults, which we are not going to use. Hence we can remove
8523 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8524 Don't warn if site-lisp directories are missing.
8525 If not installed, start from a blank load-path, since
8526 PATH_LOADSEARCH refers to the eventual installation directories.
8528 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8530 Support truncation and continuation glyphs on GUI frames, when
8531 fringes are disabled. (Bug#11832)
8532 * xdisp.c (init_iterator): Get dimensions of truncation and
8533 continuation glyphs even if on GUI frames.
8534 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8535 or both, are absent.
8536 (start_display, move_it_in_display_line_to): Handle the case of a
8537 GUI frame without a fringe to display continuation or truncation
8539 (insert_left_trunc_glyphs): Support GUI frames: make sure
8540 truncation glyphs overwrite enough glyphs from the current line to
8541 have sufficient space in pixels.
8542 (display_line): Support truncation and continuation glyphs on GUI
8543 frames. If some spare pixels are left on the line after inserting
8544 the truncation glyphs, fill that space with a stretch glyph of a
8545 suitably computed width.
8547 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8548 produce_glyphs, to support GUI sessions.
8550 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8552 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8554 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8556 Do not require float-time's arg to fit in time_t (Bug#11825).
8557 This works better on hosts where time_t is unsigned, and where
8558 float-time is applied to the (negative) difference between two times.
8559 * editfns.c (decode_time_components): Last arg is now double *,
8560 not int *, and means to store all the result as a double, without
8561 worrying about whether the seconds part fits in time_t.
8562 All callers changed.
8563 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8564 All callers changed.
8565 (Ffloat_time): Do not fail merely because the specified time falls
8566 outside of time_t range.
8568 2012-07-07 Glenn Morris <rgm@gnu.org>
8570 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8595 * w32fns.c (Fx_change_window_property): Doc fix.
8597 * w32fns.c (Fx_window_property): Accept the same arguments as the
8598 X Windows version. Doc fix.
8599 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8601 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8602 Eli Zaretskii <eliz@gnu.org>

8610 * process.c: Avoid unnecessary calls to gettime.
8611 (wait_reading_process_output): Don't get the time of day
8612 when gobbling data immediately and not waiting, as there's no need
8613 for it in that case. This removes a FIXME.
8615 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8617 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8618 is defined (Bug#11768).

8624 if buffer is not multibyte.
8625 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8626 Call byte_char_debug_check with correct arguments.
8628 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8630 Compile marker debugging code only if ENABLE_CHECKING is defined.
8631 * marker.c (byte_char_debug_check, count_markers):
8632 Use only if ENABLE_CHECKING is defined.
8633 (byte_debug_flag): Remove.
8634 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8635 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8637 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8639 Avoid code repetition in marker-related functions.
8640 * marker.c (attach_marker): New function.

8643 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8644 Consistently rename charno to charpos.
8645 (marker_position): Add eassert.
8646 (marker_byte_position): Convert to eassert.

8658 * lisp.h (build_marker): New prototype.
8659 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
8660 * composite.c (autocmp_chars): Likewise.
8661 * editfns.c (buildmark): Remove.
8662 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8663 (save_restriction_save): Use build_marker.
8664 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8665 * window.c (save_window_save): Likewise.
8667 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8672 (delete_all_overlays, Fdelete_overlay): Use it.
8673 * minibuf.c (get_minibuffer): Fix comment.
8675 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8677 Port to OpenBSD 5.1 amd64.
8678 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8679 This is needed for OpenBSD, and should be harmless on all BSD systems.
8680 Also, include <sys/sysctl.h>, as it should be available on all
8681 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8682 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8683 use p_pid member, not kp_proc.pid.
8685 2012-07-06 Glenn Morris <rgm@gnu.org>
8687 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8689 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8691 More xmalloc and related cleanup.
8692 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

8700 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8702 Omit needless casts involving void * pointers and allocation.
8703 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8704 as the former is more robust if P's type is changed.
8705 Prefer xzalloc to xmalloc + memset 0.
8706 Simplify malloc-or-realloc to realloc.
8707 Don't worry about xmalloc returning a null pointer.
8708 Prefer xstrdup to xmalloc + strcpy.
8709 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8711 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8712 alloca of a constant.

8716 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8717 hscroll is larger than the line width. Fixes long and futile
8718 looping inside extend_face_to_end_of_line (on a TTY) producing
8719 glyphs that are not needed and thrown away.
8721 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8723 * marker.c (set_marker_restricted_both): Simplify by using
8726 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8735 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8736 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8737 followed by gtk_box_set_homogeneous (Bug#11768).
8738 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8739 (update_theme_scrollbar_width, xg_create_scroll_bar):
8740 Use gtk_scrollbar_new (Bug#11768).
8741 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8742 (is_box_type): New function (Bug#11768).

8749 * xdisp.c (window_hscroll_limited): New function.
8750 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8751 coordinates when window's hscroll is set to insanely large
8754 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8756 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8815 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8817 * fileio.c (time_error_value): Check the right error number.
8818 Problem reported by Troels Nielsen in
8819 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

8823 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8824 This should be fixed in a better way; see Eli Zaretskii in
8825 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8826 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8828 * fileio.c (time_error_value): Rename from special_mtime.
8829 The old name's problems were noted by Eli Zaretskii in
8830 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8832 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8833 This variable's comment says Emacs needs at least one GDB-visible
8834 symbol of type enum pvec_type, to work around GDB problems.
8835 The symbol's value doesn't matter.
8837 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8838 that causes compilation to fail on pre-C99 compilers.
8840 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8842 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8853 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8854 * lisp.h (enum pvec_type): Use fewer bits.
8855 (PSEUDOVECTOR_SIZE_BITS): New constant.
8856 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8857 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8858 change in pvec_type.

8865 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8866 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8867 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8868 abusing vector->header.next.nbytes.
8869 (live_vector_p): Use PVEC_TYPE.
8870 (mark_object): Adapt code to extract pvectype. Use switch.
8872 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8874 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8875 Tighten new eassert a bit.
8877 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8879 Fix compilation with --enable-gcc-warnings and -O1
8881 * doprnt.c (doprnt): Change type of tem to int, initialize
8882 to avoid compiler warning. Add eassert.
8883 * search.c (simple_search): Initialize match_byte to avoid
8884 compiler warning. Add eassert.
8886 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8888 Avoid weird behavior with large horizontal scrolls.
8889 Without this change, for example, large hscroll values would
8890 mess up Emacs's display on Fedora 15 x86, presumably due to
8891 overflows in int calculations in the display code.
8892 Also, if buffers had long lines, Emacs would freeze.
8893 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8894 (set_window_hscroll): New function, containing the old guts of
8895 Fset_window_hscroll. Return the clipped value.
8896 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8897 This avoids the need to check against PTRDIFF_MAX.
8899 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8901 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

8905 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8907 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8908 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8909 since GCC 4.4.6 issues a bogus warning for them.
8911 Fix bugs in file timestamp newness comparisons.
8912 * fileio.c (Ffile_newer_than_file_p):
8913 * lread.c (Fload): Use full timestamp resolution of files,
8914 not just the 1-second resolution, so that files that are only
8915 slightly newer still count as newer.
8916 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8917 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8919 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8921 * fileio.c: Improve handling of file time marker. (Bug#11852)
8922 (special_mtime): New function.

8928 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8929 marker for non-existing file. (Bug#11852)
8931 2012-07-03 Glenn Morris <rgm@gnu.org>
8933 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8934 and did not make it into globals.h).
8936 2012-07-03 Tom Tromey <tromey@redhat.com>

8974 2012-07-03 Glenn Morris <rgm@gnu.org>
8976 * lisp.h (Frandom): Make it visible to C.
8977 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8978 buffer for invisible buffers. (Bug#1229)

8982 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8983 values which aren't power of 2.
8984 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8985 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users

8996 * alloc.c (allocate_vector_block): Remove redundant
8997 calls to mallopt if DOUG_LEA_MALLOC is defined.
8998 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8999 avoid calls to mallopt if zero_vector is returned.
9001 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9003 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9004 is enabled, avoid dereferencing NULL current_sblock if
9007 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9009 Cleanup basic buffer management.
9010 * buffer.h (struct buffer): Change layout to use generic vector
9011 marking code. Fix some comments. Change type of 'clip_changed'
9012 to bitfield. Remove unused #ifndef old.
9013 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

9024 (mark_object): Use it. Adjust marking of misc objects
9025 and related comments.
9027 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9029 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9030 wrapper that is not needed because the wrapped code is a no-op (zero
9031 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9032 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9034 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9036 * alloc.c (mark_buffer): Simplify. Remove prototype.
9037 (mark_object): Add comment. Reorganize marking of vector-like
9038 objects. Use CHECK_LIVE for all vector-like objects except buffers
9039 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9040 Avoid redundant calls to mark_vectorlike for bool vectors.
9042 2012-06-30 Glenn Morris <rgm@gnu.org>
9044 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9046 * epaths.in (PATH_SITELOADSEARCH): New.
9047 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9048 This is rather than relying on --enable-locallisppath elements
9049 having "site-lisp" in their names. (Bug#10208#25, 11658)
9051 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9053 * w32proc.c (sys_select): Accept and ignore one more argument.
9055 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9057 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9058 (pselect) [!MS_DOS]: Redirect to sys_select.
9060 * sysdep.c: Don't include dos.h and dosfns.h.
9062 * process.c (sys_select):
9063 * msdos.c (sys_select): Accept one more argument and ignore it.
9065 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9066 adapt data types and code to that.
9069 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9070 which clashes with the gnulib function of the same name.
9072 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9074 * font.c (font_style_to_value, font_style_symbolic)
9075 (font_prop_validate_style): Add type checks for values in
9078 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9080 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9083 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9085 * xdisp.c (try_window_id): Undo last change.
9087 * w32.c (getwd): Adjust commentary about startup_dir.
9088 (init_environment): Always call sys_access, even in non-MSVC
9089 builds. Don't chdir to the directory of the Emacs executable.
9090 This undoes code from 1997 which was justified by the need to
9091 "avoid conflicts when removing and renaming directories". But its
9092 downside was that every relative file name was being interpreted
9093 relative to the directory of the Emacs executable, which can never
9094 be TRT. In particular, it broke sys_access when called with
9095 relative file names.
9096 (sys_access): Map GetLastError to errno.
9098 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9100 * window.h (struct window): Change type of 'fringes_outside_margins'

9110 Add QUIT to make the loop interruptible.
9112 2012-06-29 Glenn Morris <rgm@gnu.org>
9114 * charset.c (init_charset): Make lack of etc/charsets fatal.
9116 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

9133 Avoid integer overflow on scroll-left and scroll-right.
9134 * window.c (HSCROLL_MAX): New macro.
9135 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9136 overflow when requested scroll falls outside ptrdiff_t range.

9140 * window.h (struct window): Change type of 'hscroll',
9141 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9142 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9143 Adjust users accordingly.
9144 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9145 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9146 from EMACS_INT to ptrdiff_t.
9147 (make_window): Omit redundant initialization.
9149 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9153 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9155 * window.h (struct window): Change type of 'use_time' and
9156 'sequence_number' from Lisp_Object to int.

9222 * alloc.c (allocate_string): Omit intervals initialization.
9223 * alloc.c (make_uninit_multibyte_string): Initialize intervals

9278 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9280 * alloc.c: Remove build_string.
9281 * lisp.h: Define build_string as static inline. This provides
9282 a better opportunity to optimize away calls to strlen when the
9283 function is called with compile-time constant argument.
9284 * image.c (imagemagick_error): Convert to build_string.
9285 * w32proc.c (sys_spawnve): Likewise.
9286 * xterm.c (x_term_init): Likewise.
9288 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9290 Use sprintf return value instead of invoking strlen on result.
9291 In the old days this wasn't portable, since some sprintf
9292 implementations returned char *. But they died out years ago and
9293 Emacs already assumes sprintf returns int.
9294 Similarly for float_to_string.
9295 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9296 * ccl.c (ccl_driver):
9297 * character.c (string_escape_byte8):

9300 * print.c (print_object):
9301 * xdisp.c (message_dolog):
9302 * xfns.c (syms_of_xfns):
9303 Use sprintf or float_to_string result to avoid need to call strlen.
9304 * data.c (Fnumber_to_string):
9305 Use make_unibyte_string, since the string must be ASCII.
9306 * lisp.h, print.c (float_to_string): Now returns int length.
9307 * term.c (produce_glyphless_glyph):
9308 Use sprintf result rather than recomputing it.
9310 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9311 * Makefile.in (ALL_CFLAGS):
9312 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9313 * gmalloc.c, regex.c: Include <config.h> unconditionally.

9317 * dispextern.h (xstrcasecmp): Define to library function
9318 strcasecmp if available.
9319 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

9334 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9336 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9337 sprintf already null-terminates its output.
9339 * xfns.c (x_window): Remove redundant cast.
9341 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9343 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9344 `const char *' to `char *' to avoid compiler warning.
9346 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9348 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9349 instead of truncating it to 63 (admittedly a generous limit).
9351 * process.c: Fix spelling and caps in comments.
9353 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9355 * emacs.c (setpgrp): Remove definition, unused.

9401 * sound.c (sound_warning, parse_sound):
9402 Remove unnecessary forward decls.
9404 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9406 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

9408 * dispnew.c (Fsleep_for, sit_for):
9409 * keyboard.c (kbd_buffer_get_event):
9410 * process.c (Faccept_process_output):
9411 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9412 This improves on the previous patch, which introduced a bug
9413 when time_t is unsigned and as wide as intmax_t.
9414 See <http://bugs.gnu.org/9000#51>.
9416 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9425 * makefile.w32-in: Update dependencies.
9427 * w32.c (ltime): Add return type and declare static.

9430 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9432 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9433 Privately reported by Herbert J. Skuhra.
9434 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9436 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9437 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9439 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9441 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9442 last argument of make_unibyte_string.
9444 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9445 language ID in the event parameters.
9447 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9448 event.code, not the obscure "character set ID".
9450 2012-06-23 Chong Yidong <cyd@gnu.org>
9452 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9454 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9456 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

9471 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9472 Privately reported by Herbert J. Skuhra.

9479 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9481 Support higher-resolution time stamps (Bug#9000).
9482 The time stamps are only nanosecond-resolution at the C level,
9483 since that's the best that any real-world system supports now.
9484 But they are picosecond-resolution at the Lisp level, as that's
9485 easy, and leaves room for future OS improvements.
9487 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9490 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9491 Don't get current time unless it's needed.
9493 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9494 now provides it if it's absent.
9495 (start_atimer): Port to higher-res time stamps.
9496 Check for time stamp overflow. Don't get current time more
9497 often than is needed.
9499 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9500 Include systime.h, not time.h.
9501 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9503 * dired.c: Include stat-time.h.
9504 (Ffile-attributes): File times now have higher resolution.
9506 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9507 (struct image): Timestamp now has higher resolution.
9509 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9510 has at least microseconds now. All uses removed.
9511 (update_frame, update_single_window, update_window, update_frame_1)
9512 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9513 (duration_to_sec_usec): Remove; no longer needed.
9515 * editfns.c (time_overflow): Now extern.
9516 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9517 (float-time, Fformat_time_string, Fcurrent_time_string)
9518 (Fcurrent_time_zone): Accept and generate higher-resolution
9520 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9521 (decode_time_components, lisp_seconds_argument): New functions.
9522 (make_time): Now static.
9523 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9524 Report an error if the time is invalid, rather than having the caller
9527 * fileio.c: Include <stat-time.h>
9528 (Fcopy_file): Copy higher-resolution time stamps.
9529 Prefer to set the time stamp via a file descriptor if that works.
9530 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9531 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9532 (Fvisited_file_modtime, Fset_visited_file_modtime):
9533 Support higher-resolution time stamps.
9535 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9537 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9539 * image.c (prepare_image_for_display, clear_image_cache)
9540 (lookup_image): Port to higer-resolution time stamps.

9546 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9547 Port to higher-resolution time stamps. Do not assume time_t is signed.
9548 (decode_timer): New function. Timers are now vectors of length 9,
9549 not 8, to accommodate the picosecond component.
9550 (timer_check_2): Use it.
9552 * nsterm.m (select_timeout, timeval_subtract): Remove.
9553 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9554 as they're a bit more accurate and handle overflow better.

9556 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9557 * nsterm.h (ns_select): Adjust prototype.
9559 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9560 us-resolution time stamps.
9561 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9563 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9565 * lisp.h (time_overflow): New decl.
9566 (wait_reading_process_output): First arg is now intmax_t, not int,
9567 to accommodate larger waits.
9569 * process.h (struct Lisp_Process.read_output_delay):
9570 Now counts nanoseconds, not microseconds.
9571 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

9574 (wait_reading_process_output):
9575 Port to ns-resolution time stamps.
9576 (Faccept_process_output, wait_reading_process_output):
9577 Check for time stamp overflow. Do not assume time_t is signed.
9578 (select_wrapper): Remove; we now use pselect.
9579 (Fprocess_attributes): Now generates ns-resolution time stamps.
9581 * sysdep.c: Include utimens.h. Don't include utime.h
9582 or worry about struct utimbuf; gnulib does that for us now.
9583 (gettimeofday): Remove; gnulib provides a substitute.
9584 (make_timeval): New function.
9585 (set_file_times): Now sets ns-resolution time stamps.
9586 New arg FD; all uses changed.
9587 (time_from_jiffies, ltime_from_jiffies, get_up_time)

9589 Now returns ns-resolution time stamp. All uses changed.
9590 Check for time stamp overflow.
9592 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9593 provides a substitute now.
9595 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9596 since it guarantees struct timespec.
9597 (EMACS_TIME): Now struct timespec, so that we can support
9598 ns-resolution time stamps.
9599 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9600 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9601 (EMACS_USECS): Remove.
9602 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9603 so multiply the arg by 1000 before storing it.
9604 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9606 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

9613 (make_timeval, make_lisp_time, decode_time_components): New decls.
9614 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9615 that it mishandled time_t overflow. You can't compare by subtracting!
9616 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9617 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9619 * term.c: Include <sys/time.h>.
9620 (timeval_to_Time): New function, for proper overflow wraparound.
9621 (term_mouse_position, term_mouse_click): Use it.
9623 * undo.c (record_first_change): Support higher-resolution time stamps
9625 (Fprimitive_undo): Use them when restoring time stamps.

9628 (w32_get_internal_run_time):
9629 Port to higher-resolution Emacs time stamps.
9630 (ltime): Now accepts single 64-bit integer, as that's more convenient

9640 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9641 Check for time stamp overflow, and support ns-resolution time stamps.
9643 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9644 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9645 (timeval_subtract): Remove; no longer needed.
9646 (XTflash, XTring_bell, x_wait_for_event):
9647 Port to ns-resolution time stamps. Don't assume time_t is signed.

9653 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9655 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9656 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9657 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9658 staticidx goes up to 1597 out of 1600 = 0x640.)
9660 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9662 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9663 Otherwise, the umask might be mistakenly 0 while handling input signals.

9673 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9674 access to `contents' member of Lisp_Vector objects with AREF and ASET
9677 2012-06-19 Chong Yidong <cyd@gnu.org>
9679 * frame.c (delete_frame): When selecting a frame on a different
9680 text terminal, do not alter the terminal's top-frame.

9684 (unwind_format_mode_line): Restore them.
9685 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9687 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9688 since tty frames can be explicitly named.
9689 (prepare_menu_bars): Likewise.
9691 * term.c (Ftty_top_frame): New function.
9693 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9695 Port byte-code-meter to modern targets.
9696 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9697 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9698 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9699 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

9706 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9708 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9709 gets killed during executing of this function (Bug#11665).
9710 Try to always return Qt when the buffer has been actually killed.
9711 (Vkill_buffer_query_functions): In doc-string say that functions
9712 run by this hook should not change the current buffer.
9714 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9716 Fix recently-introduced process.c problems found by static checking.
9717 * process.c (write_queue_push, write_queue_pop, send_process):

9737 This removes the need for CHECK.
9738 (CHECK): Remove. Its comments about always evaluating its
9739 argument were confusing, as 'eassert' typically does not evaluate
9742 * coding.c (produce_chars): Use ptrdiff_t, not int.
9744 * xterm.c (x_draw_underwave): Check for integer overflow.
9745 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10020 * xdisp.c (vmessage): Treat frame message as multibyte.
10021 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10022 would generate the diagnostic "Making \302\247 buffer-local while

10027 * dispnew.c (showing_window_margins_p): Undo last change, which
10028 was done due to an inadvertent commit.

10049 Block-based vector allocation of small vectors.
10050 * lisp.h (struct vectorlike_header): New field `nbytes',
10051 adjust comment accordingly.
10052 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10053 to denote vector blocks. Adjust users (live_vector_p,
10054 mark_maybe_pointer, valid_lisp_object_p) accordingly.

10076 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10078 * doprnt.c (doprnt): Truncate multibyte char correctly.
10079 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10080 would mishandle a string argument "Xc" if X was a multibyte
10081 character of length 2: it would truncate after X's first byte
10082 rather than including all of X.
10084 2012-06-06 Chong Yidong <cyd@gnu.org>
10086 * buffer.c (word_wrap): Doc fix.
10088 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10100 binary via PaX flags if the paxctl utility is available.
10101 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10102 Restore PaX flags to their default. (Bug#11398)
10104 2012-06-03 Chong Yidong <cyd@gnu.org>
10106 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10107 buffer (Bug#11226).

10114 position is past the end of the mode line string.
10116 * buffer.c (buffer_local_value_1): New function, split from
10117 Fbuffer_local_value; can return Qunbound.
10118 (Fbuffer_local_value): Use it.
10119 (Vmode_line_format): Docstring tweaks.
10121 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10133 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10135 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10136 Convert pctcpu and pctmem to Lisp float properly.
10137 Let the compiler fold better, as 100.0/0x8000 is exact.
10139 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10141 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10144 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10148 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10150 For a 'struct window', replace some Lisp_Object fields to
10151 bitfields where appropriate, remove unused fields.
10152 * window.h (struct window): Remove unused 'last_mark_x' and
10153 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10154 change its type from Lisp_Object to bitfield.
10155 Change type of 'force_start', 'optional_new_start',
10156 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10157 fields from Lisp_Object to bitfield. Adjust users accordingly.
10159 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10161 Pacify gcc -Wdouble-precision when using Xaw.
10162 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10163 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10164 Use 'float' consistently, rather than 'float' in most places
10165 and 'double' in a couple of places.
10167 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10169 * xdisp.c (handle_stop): Detect whether we have overlay strings
10170 loaded by testing it->current.overlay_string_index to be
10171 non-negative, instead of checking whether n_overlay_strings is
10172 positive. (Bug#11587)
10174 2012-05-31 Chong Yidong <cyd@gnu.org>
10176 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10180 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10182 * search.c (search_buffer): Remove calls to
10183 r_alloc_inhibit_buffer_relocation, as it is now called by
10184 maybe_unify_char, which was the cause of relocation of buffer text
10187 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10189 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10190 for the duration of call to load_charset, to avoid problems with
10191 callers of maybe_unify_char that access buffer text through C
10194 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10195 decrement the inhibition flag, instead of just setting or
10198 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10200 Remove obsolete '#define static' cruft.
10201 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10202 This #undef was "temporary" in 2000; it is no longer needed
10203 now that '#define static' has gone away.
10204 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10205 (gray_bitmap_bits): Remove; no longer needed.
10206 All uses replaced with definiens.
10207 * xterm.c: Include "bitmaps/gray.xbm".
10209 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

10212 The following changes affect the code only when profiling.
10213 * dispnew.c (__executable_start): Rename from safe_bcopy.
10214 Define only on platforms that need it.
10215 * emacs.c: Include <sys/gmon.h> when profiling.
10216 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10217 (__executable_start): Remove decl, since lisp.h does it now.
10218 (safe_bcopy): Remove decl; no longer has that name.
10219 (main): Coalesce #if into single bit of code, for simplicity.
10220 Cast pointers to uintptr_t, since standard libraries want integers
10222 * lisp.h (__executable_start): New decl.
10224 2012-05-31 Glenn Morris <rgm@gnu.org>
10226 * image.c (Fimagemagick_types): Doc fix.

10247 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10249 Do not create empty overlays with the evaporate property (Bug#9642).
10250 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10251 Bug#9642, but explicitly check that the buffer the overlay would
10252 be moved to is live and rearrange lines to make sure that errors
10253 will not put the overlay in an inconsistent state.
10254 (Fdelete_overlay): Cosmetics.
10256 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10258 * w32term.c (my_bring_window_to_top): New function.
10259 (x_raise_frame): Use handle returned by DeferWindowPos, which
10260 could be different from the original one.

10270 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10272 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10273 This avoids undefined behavior that might cause the eassert
10274 to not catch an out-of-range value.
10276 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10278 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10279 Update dependencies.
10281 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10283 * bidi.c (bidi_mirror_char): Fix last change.
10285 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10290 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10292 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10293 Only r_alloc_inhibit_buffer_relocation needed to be added;
10294 the others were already declared.
10296 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10297 before checking whether it's out of range. Put the check inside
10299 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10301 2012-05-27 Ken Brown <kbrown@cornell.edu>
10303 * callproc.c (Fcall_process): Restore a line that was accidentally
10304 commented out in the 2011-02-13 change (bug#11547).
10306 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10308 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10309 defined on ralloc.c.
10311 * buffer.c [REL_ALLOC]: Remove prototypes of
10312 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10313 they are now on lisp.h.
10315 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10317 * search.c (search_buffer): Use it to inhibit relocation of buffer
10318 text while re_search_2 is doing its job, because re_search_2 is
10319 passed C pointers to buffer text. (Bug#11519)
10321 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10322 Update value to 24.
10324 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10325 state after an additional call to move_it_in_display_line_to, keep
10326 the values of it->max_ascent and it->max_descent found for the
10328 (pos_visible_p): Revert the comparison against bottom_y to what it
10329 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10332 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10334 Fix coding-related core dumps with gcc -ftrapv.
10335 The code was computing A - B, where A and B are pointers, and B is
10336 random garbage. This can lead to core dumps on platforms that
10337 have special pointer registers, and it also leads to core dumps on
10338 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10339 A - B only when B is initialized properly.
10340 * coding.c (coding_set_source, coding_set_destination): Return void.
10341 (coding_change_source, coding_change_destinations): New functions,
10342 with the old behaviors of coding_set_source and coding_set_destination.
10343 All callers that need an offset changed to use these new functions.
10345 2012-05-26 Glenn Morris <rgm@gnu.org>
10347 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

10353 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10355 * w32console.c: Include window.h.
10356 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10358 (initialize_w32_display): Initialize mouse-highlight data.
10360 * w32inevt.c: Include termchar.h and window.h.
10361 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10362 moves, call note_mouse_highlight. If help_echo changed, call
10363 gen_help_event to produce help-echo message in the echo area.
10364 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10367 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10369 * lread.c (read1): Simplify slightly to avoid an overflow warning
10370 with GCC 4.7.0 on x86-64.
10372 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10374 * bidi.c (bidi_mirror_char): Revert last change: an int is
10375 definitely wide enough here.
10377 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

10387 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10389 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10391 Use int, not EMACS_INT, where int is wide enough.
10392 (inhibit_garbage_collection, Fgarbage_collect):
10393 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10394 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10395 int might not be wide enough.
10396 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10397 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10398 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10399 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10400 (bidi_level_of_next_char, bidi_move_to_visually_next):
10401 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10402 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10403 (Fkill_buffer, Fset_buffer_major_mode)
10404 (advance_to_char_boundary, Fbuffer_swap_text)

10406 (overlay_touches_p, struct sortvec, record_overlay_string)
10407 (overlay_strings, recenter_overlay_lists)

10413 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10414 (validate_region): Omit unnecessary test for b <= e,
10415 since that's guaranteed by the previous test.
10416 (adjust_overlays_for_delete): Avoid pos + length overflow.
10417 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10418 (report_overlay_modification):
10419 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10420 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10421 Omit pointer cast, which isn't needed anyway, and doesn't work
10422 after the EMACS_INT -> ptrdiff_t change.
10423 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10424 * buffer.h: Adjust decls to match defn changes elsewhere.
10425 (struct buffer_text, struct buffer):
10426 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10427 Use EMACS_INT, not int, where int might not be wide enough.
10428 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10429 not int, to avoid needless 32-bit limit on 64-bit hosts.
10430 (exec_byte_code): Use tighter memory-full test, one that checks
10431 for alloca overflow. Don't compute the address of the object just
10432 before an array, as that's not portable. Use EMACS_INT, not
10433 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10434 * callint.c (Fcall_interactively):
10435 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10436 * callproc.c (call_process_kill, Fcall_process):

10446 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10447 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10448 (casify_object): Avoid integer overflow when overallocating buffer.
10449 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10450 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10451 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10452 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10453 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10454 integers are now checked earlier. All uses replaced with XINT.
10456 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10457 For CCL_MapSingle, check that content and value are in int range.
10458 (ccl_driver, Fregister_code_conversion_map):
10459 Check that Vcode_version_map_vector is a vector.
10460 (resolve_symbol_ccl_program): Check that vector header is in range.
10461 Always copy the vector, so that we can check its contents reliably
10462 now rather than having to recheck each instruction as it's being
10463 executed. Check that vector words fit in 'int'.
10464 (ccl_get_compiled_code, Fregister_ccl_program)
10465 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10466 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10468 contents are in range.
10469 (Fccl_execute_on_string): Check that status is in range.

10471 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

10479 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10480 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10481 avoid mishandling large integers.

10491 (Fdefine_charset_internal): Check ranges here, more carefully.
10492 Don't rely on undefined behavior with signed left shift overflow.
10493 Don't assume unsigned int fits into fixnum, or that fixnum fits
10494 into unsigned int. Don't require max_code to be a valid fixnum;
10495 that's not true for gb10830 4-byte on a 32-bit host. Allow
10496 invalid_code to be a cons, for the same reason. Require code_offset
10497 to be a character. Avoid int overflow if max_char is close
10499 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10500 this is intended anyway and avoids some undefined behavior.
10501 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10502 INDEX_TO_CODE_POINT, as that's what it expects.
10503 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10504 * charset.h (DECODE_CHAR): Return int, not unsigned;
10505 this is what was intended anyway, and it avoids undefined behavior.

10507 integer-overflow issues.
10508 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10509 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10510 where the argument is EMACS_INT, and this behavior is not intended.
10511 * chartab.c (Fmake_char_table, Fset_char_table_range)
10512 (uniprop_get_decoder, uniprop_get_encoder):
10513 Don't assume fixnum fits in int.
10514 * cmds.c (move_point): New function, that does the gist of
10515 Fforward_char and Fbackward_char, but does so while checking
10516 for integer overflow more accurately.
10517 (Fforward_char, Fbackward_char): Use it.
10518 (Fforward_line, Fend_of_line, internal_self_insert)

10520 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11125 doesn't matter here.
11126 (get_next_display_element, next_element_from_display_vector):
11127 Use int, not EMACS_INT, when int is wide enough.
11128 (start_hourglass): Use duration_to_sec_usec to do proper
11129 overflow checking on durations.

11179 2012-05-25 Glenn Morris <rgm@gnu.org>
11181 * lisp.mk (lisp): Update for more files being compiled now.
11183 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11185 * lread.c: Remove `read_pure' which makes no difference.
11186 (read_pure): Remove var.
11187 (unreadpure): Remove function.
11188 (readevalloop): Don't call read_list with -1 flag.
11189 (read1, read_vector): Don't test read_pure any more.

11198 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11200 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11201 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11203 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11206 This directory predates autoconf and is no longer needed nowadays.
11207 Move its few remaining bits of functionality to where they're needed.
11208 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

11210 * m/template.h: Remove.
11211 * Makefile.in (M_FILE): Remove. All uses removed.
11212 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11213 * lisp.h (USE_LSB_TAG):
11214 * mem-limits.h (EXCEEDS_LISP_PTR):
11215 Use VAL_MAX, not VALBITS, in #if.
11216 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11217 (EMACS_UINT): Define unconditionally now.
11218 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11219 (BITS_PER_EMACS_INT): New constants, replacing
11220 what used to be in config.h, but not useful in #if.
11221 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11222 define them any more.
11223 (VAL_MAX): New macro.
11225 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11226 BITS_PER_EMACS_INT, in #if.
11227 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11228 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11229 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11230 * s/ms-w32.h (DATA_START):
11231 Move here from removed file m/intel386.h.
11232 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11233 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11235 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11237 Assume C89 or later.
11238 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

11258 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11260 2012-05-19 Ken Brown <kbrown@cornell.edu>
11262 * xfns.c (x_in_use): Remove `static' qualifier.
11263 * xterm.h (x_in_use): Declare.
11264 * xgselect.c: Include xterm.h.
11265 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11266 and `display_arg' (bug#9754).
11268 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11270 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11272 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11273 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11275 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11277 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11279 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11280 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11282 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11283 reference to image_cache->refcount.
11284 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11286 2012-05-17 Juri Linkov <juri@jurta.org>
11288 * search.c (Fword_search_regexp, Fword_search_backward)
11289 (Fword_search_forward, Fword_search_backward_lax)
11290 (Fword_search_forward_lax): Move functions to isearch.el
11291 (bug#10145, bug#11381).
11293 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11295 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11297 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11299 * lread.c (init_obarray): Declare Qt and Qnil as special.
11301 2012-05-14 Glenn Morris <rgm@gnu.org>
11303 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11304 Put "libexec" before "bin", for the sake of init_callproc_1.
11306 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11308 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11310 * unexaix.c: Port to more-recent AIX compilers.
11311 (report_error, report_error_1, make_hdr, copy_sym)
11312 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11313 Make arguments const char *, not char *, to avoid violations of C
11314 standard and to fix some AIX warnings reported by Gilles Pion.
11316 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11318 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11319 already have overlays loaded.
11320 (handle_single_display_spec): Before returning without displaying
11321 fringe bitmap, synchronize the bidi iterator with the main display
11322 iterator, by calling iterate_out_of_display_property.
11323 (iterate_out_of_display_property): Detect buffer iteration by
11324 testing that it->string is a Lisp string.
11325 (get_next_display_element): When the current object is exhausted,
11326 and there's something on it->stack, call set_iterator_to_next to
11327 proceed with what's on the stack, instead of returning zero.
11328 (set_iterator_to_next): If called at the end of a Lisp string,
11329 proceed to consider_string_end without incrementing string
11330 position. Don't increment display vector index past the end of
11331 the display vector. (Bug#11417)
11332 (pos_visible_p): Don't report a position visible when move_it_to
11333 stopped at the last line of window, which happens to be scanned
11334 backwards by the bidi iteration. (Bug#11464)
11336 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11338 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11339 and right-margin display specs even if the spec is invalid or we
11340 are on a TTY, and thus unable to display on the fringes.
11341 That's because the text with the property will not be displayed anyway,
11342 so we need to signal to the caller that this is a "replacing"
11343 display spec. This fixes display when the spec is invalid or we
11346 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11348 * unexaix.c (make_hdr): Fix typo in prototype.
11349 This bug broke the build on AIX. Problem reported by Gilles Pion.
11351 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11353 * keyboard.c (kbd_buffer_get_event): Read special events also in
11354 batch mode. (Bug#11415)
11356 2012-05-12 Glenn Morris <rgm@gnu.org>
11358 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11360 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11362 * lisp.mk (lisp): Add newcomment.elc.
11364 2012-05-12 Glenn Morris <rgm@gnu.org>
11366 * Makefile.in (MKDIR_P): New, set by configure.
11367 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11369 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11371 Remove unused function hourglass_started.
11372 * dispextern.h (hourglass_started):
11373 * w32fns.c (hourglass_started):
11374 * xdisp.c (hourglass_started): Remove.
11376 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11378 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11379 Update dependencies.
11381 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11383 * xgselect.c (xg_select): Put maxfds+1 into a var.
11384 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11386 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11388 2012-05-10 Dave Abrahams <dave@boostpro.com>
11390 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11391 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11393 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11395 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11396 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11397 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11398 Initialize xd_registered_buses.
11400 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11402 Untag more efficiently if USE_LSB_TAG.
11403 This is based on a proposal by YAMAMOTO Mitsuharu in
11404 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11405 For an admittedly artificial (nth 8000 longlist) benchmark on
11406 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11407 Emacs's overall text size by 1%.
11408 * lisp.h (XUNTAG): New macro.
11409 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11410 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11411 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11412 * eval.c (Fautoload):
11413 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11414 * frame.h (XFRAME): Use XUNTAG.
11416 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11417 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11418 Remove unportable assumptions about print widths of types like
11420 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11421 intptr_t when converting between pointer and integer, to avoid GCC
11422 warnings about wrong width.
11424 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11426 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11427 stack for each reader_thread, instead of defaulting to 8MB
11428 determined by the linker. This avoids failures in creating
11429 subprocesses on Windows 7, see the discussion in this thread:
11430 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11432 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11434 Fix up display of the *Minibuf-0* buffer in the mini window.
11435 * keyboard.c (read_char): Don't clear the echo area if there's no
11437 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11438 contents of *Minibuf-0*) if there's no message displayed in its stead.
11440 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11442 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11445 2012-05-06 Chong Yidong <cyd@gnu.org>
11447 * lisp.mk (lisp): Update.
11449 2012-05-05 Jim Meyering <meyering@redhat.com>
11451 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11453 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11455 * data.c (PUT_ERROR): New macro.
11456 (syms_of_data): Use it. Add new error type `user-error'.
11457 * undo.c (user_error): New function.
11458 (Fprimitive_undo): Use it.
11459 * print.c (print_error_message): Adjust print style for `user-error'.
11460 * keyboard.c (user_error): New function.
11461 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11463 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11465 Do not limit current-time-string to years 1000..9999.
11466 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11467 (Fcurrent_time_string): Support any year that is supported by the
11468 underlying localtime representation. Don't use asctime, as it
11469 has undefined behavior for years outside the range -999..9999.
11471 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11473 Fix race conditions involving setenv, gmtime, localtime, asctime.
11474 Without this fix, interrupts could mess up code that uses these
11475 nonreentrant functions, since setting TZ invalidates existing
11476 tm_zone or tzname values, and since most of these functions return
11477 pointers to static storage.
11478 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11479 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11480 Grow the critical sections to include not just invoking
11481 localtime/gmtime, but also accessing these functions' results
11482 including their tm_zone values if any, and any related TZ setting.
11483 (format_time_string): Last arg is now struct tm *, not struct tm **,
11484 so that the struct tm is saved in the critical section.
11485 All callers changed. Simplify allocation of initial buffer, partly
11486 motivated by the fact that memory allocation needs to be outside
11487 the critical section.
11489 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11491 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11492 with RESET_INTERVAL.
11494 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11495 Remove duplicated buffer name initialization.
11497 2012-05-02 Jim Meyering <jim@meyering.net>
11499 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11501 * xfns.c (x_window): Use xstrdup (Bug#11375).
11503 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11505 * xdisp.c (pos_visible_p): If already at a newline from the
11506 display string before the 'while' loop, don't walk back the glyphs
11507 from it3.glyph_row. Solves assertion violation when the display
11508 string begins with a newline (egg.el). (Bug#11367)
11510 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11512 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11515 2012-05-01 Glenn Morris <rgm@gnu.org>
11517 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11518 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11519 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11520 All were removed before 23.1.
11522 * dispnew.c: Remove HAVE_LIBNCURSES test;
11523 it is always true on relevant platforms.
11525 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11526 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

11536 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11538 Do not avoid creating empty evaporating overlays (Bug#9642).
11539 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11540 That is, do not delete an evaporating overlay if it becomes
11541 empty after its bounds are adjusted to fit within its buffer.
11542 This fix caused other problems, and I'm reverting it until we get
11543 to the bottom of them.
11545 2012-04-27 Chong Yidong <cyd@gnu.org>
11547 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11549 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11551 * xdisp.c (pos_visible_p): If the window start position is beyond
11552 ZV, start the display from buffer beginning. Prevents assertion
11553 violation in init_iterator when the minibuffer window is scrolled
11554 via the scroll bar.
11556 * window.c (window_scroll_pixel_based): Likewise.
11558 2012-04-27 Chong Yidong <cyd@gnu.org>

11565 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11567 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11569 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11570 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11572 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11574 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11575 display element, check also the underlying string or buffer
11576 character. (Bug#11341)
11578 * w32menu.c: Include w32heap.h.
11579 (add_menu_item): If the call to AppendMenuW (via
11580 unicode_append_menu) fails, disable Unicode menus only if we are
11581 running on Windows 9X/Me.
11583 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11585 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11586 (xgetint): Add missing shift for LSB tags.
11588 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11590 * keyboard.c (read_char): Don't wipe echo area for select window

11596 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11597 manipulation of :loaded-from data.
11599 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11601 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11602 now a cons (bug#11311).
11604 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11606 Do not create empty overlays with the evaporate property (Bug#9642).
11607 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11608 if it becomes empty after its bounds are adjusted to fit within
11609 its buffer. Without this fix, in a nonempty buffer (let ((o
11610 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11611 yields an empty overlay that has the evaporate property, which is
11612 not supposed to happen.

11635 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11636 (__malloc_size_t, __malloc_ptrdiff_t):
11637 Remove. All uses removed, replaced by the definiens if needed,
11638 since we can assume C89 or better now.

11727 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11729 * sysdep.c [__FreeBSD__]: Minor cleanups.
11730 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11731 Use Emacs indenting style more consistently. Avoid some casts.
11732 Use 'double' consistently rather than mixing 'float' and 'double'.
11734 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11736 * sysdep.c (list_system_processes, system_process_attributes):
11737 Add implementation for FreeBSD (Bug#5243).

11743 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11745 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11746 It is never used otherwise.
11748 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11750 * print.c (print_preprocess): Only check print_depth if print-circle
11752 (print_object): Check for cycles even when print-circle is nil and

11757 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11758 set the status to "failed" and ensure that sentinel is run.
11760 2012-04-20 Glenn Morris <rgm@gnu.org>
11762 * process.c (Fset_process_inherit_coding_system_flag)
11763 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11791 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11792 -Wunused-result, -Wunused-variable. This should go away once
11793 the Emacs and Gnulib regex code is merged.

11813 New extern decls, to avoid calling undeclared functions.
11814 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11815 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11816 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11817 (NEED_MEM_INSERT): New macro.
11818 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11819 Remove one incorrect comment and fix another.

11825 (r_alloc_sbrk): Now static.
11827 Improve ralloc.c interface checking.
11828 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11829 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

11838 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11840 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11841 (struct Lisp_Misc_Any): Likewise.
11842 (struct Lisp_Free): Likewise.

11855 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11856 * s/netbsd.h, s/sol2-6.h:
11857 Remove definition of GC_MARK_STACK, since the default now works.
11858 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11859 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11860 no longer the default.
11861 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11863 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11865 * lread.c (lisp_file_lexically_bound_p):

11886 2012-04-11 Daniel Colascione <dancol@dancol.org>
11888 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11889 against is gone. It's better to use vfork now so that when Cygwin
11890 gains a new, working vfork, we use it automatically (bug#10398).
11892 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11913 being loaded (bug#10424).
11915 2012-04-09 Glenn Morris <rgm@gnu.org>
11917 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11918 not just in the obarray, before snarfing them. (Bug#11036)

11925 * process.c (make_process):
11926 * process.h: Add integer `gnutls_handshakes_tried' member to
11929 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
11930 Add convenience `GNUTLS_LOG2i' macro.
11932 * gnutls.c (gnutls_log_function2i): Convenience log function.
11933 (emacs_gnutls_read): Use new log functions,
11934 `gnutls_handshakes_tried' process member, and
11935 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11936 attempts per process (connection).
11938 2012-04-09 Chong Yidong <cyd@gnu.org>
11940 * eval.c (Fuser_variable_p, user_variable_p_eh)
11941 (lisp_indirect_variable): Functions deleted.
11942 (Fdefvar): Caller changed.
11944 * callint.c (Finteractive, Fcall_interactively):
11945 * minibuf.c (Fread_variable): Callers changed.
11947 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11949 * xdisp.c (set_cursor_from_row): If the display string appears in
11950 the buffer at position that is closer to point than the position
11951 after the display string, display the cursor on the first glyph of
11952 the display string. Fixes cursor display when a 'display' text
11953 property immediately follows invisible text. (Bug#11094)
11955 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11957 composite.c: use 'double' consistently
11958 * composite.c (get_composition_id): Use 'double' consistently
11959 instead of converting 'float' to 'double' and vice versa; this is
11960 easier to understand and avoids a GCC warning.
11962 2012-04-09 Glenn Morris <rgm@gnu.org>
11964 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11965 preparation for dumping it with emacs. (Bug#4789)
11966 (leimdir): New variable.
11967 ($(leimdir)/leim-list.el): New rule.
11968 (emacs$(EXEEXT)): Depend on leim-list.el.

11987 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11988 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11989 objects, as mark_maybe_pointer will catch them otherwise.
11990 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11991 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12009 [!WINDOWSNT]: New macros.
12010 (init_libxml2_functions, libxml2_loaded_p): New functions.
12011 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12012 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12013 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12014 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12016 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12017 Call init_libxml2_functions before calling libxml2 functions.
12018 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12020 * emacs.c: Don't include libxml/parser.h.
12021 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12022 xmlCleanupParser directly.
12024 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12026 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12028 * indent.c (Fvertical_motion): If there is a display string at
12029 point, use it.vpos to compute how many lines to backtrack after
12030 move_it_to point. (Bug#11133)
12032 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12034 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12035 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12036 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12037 macros related to unification of CJK characters. For the details,
12038 see the discussion following the message here:
12039 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12041 2012-04-04 Chong Yidong <cyd@gnu.org>
12043 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12045 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12047 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12048 instead of alloca. (Bug#11138)
12050 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

12055 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12057 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12058 position we get to after a call to move_it_to fails the
12059 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12060 only if we wind up in a string from display property. (Bug#11063)
12062 * window.c (Fdelete_other_windows_internal): Invalidate the row
12063 and column information about mouse highlight, so that redisplay
12064 restores it after reallocating the glyph matrices. (Bug#7464)
12066 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12067 string comes from a `display' text property, use the buffer
12068 position of that property as if we actually saw that position in
12070 (move_it_by_lines): Remove the assertion that
12071 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12072 violated when there's a before-string at the beginning of a line.
12075 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12077 * xdisp.c (append_space_for_newline): If the default face was
12078 remapped, use the remapped face for the appended newline.
12079 (extend_face_to_end_of_line): Use the remapped default face for
12080 extending the face to the end of the line.
12081 (display_line): Call extend_face_to_end_of_line when the default
12082 face was remapped. (Bug#11068)
12084 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12086 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

12104 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12105 (command_loop_1): Use it; inhibit selection update for
12106 handle-select-window too (Bug#8996).
12108 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12110 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12112 2012-03-25 Kenichi Handa <handa@m17n.org>
12114 * dispextern.h (struct glyph): Change the bit length of
12115 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12117 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12119 * s/ms-w32.h (tzname): Include time.h before redirecting to
12120 _tzname. Fixes the MSVC build. (Bug#9960)
12122 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12124 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12127 * xterm.c (XTread_socket): Only modify handling_signal if
12128 !SYNC_INPUT. (Bug#11080)
12130 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12132 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12133 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12134 when fetching a multibyte character consumes more bytes than
12135 CHAR_BYTES returns, due to unification of CJK characters in
12136 string_char. (Bug#11073)
12138 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12140 * process.c (wait_reading_process_output): Handle pty disconnect
12141 by refraining from sending oneself a SIGCHLD (bug#10933).

12165 to reflect default non-nil value of redisplay-dont-pause.
12167 2012-03-19 Kenichi Handa <handa@m17n.org>
12169 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12170 it fit in a valid range (Bug#11003).
12172 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12174 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12175 that is not from display property, accept the row as a "cursor
12176 row" if one of the string's character has a non-nil `cursor'
12177 property. Fixes cursor positioning when there are newlines in
12178 overlay strings, e.g. in icomplete.el. (Bug#11035)
12180 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12182 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12184 2012-03-12 Chong Yidong <cyd@gnu.org>
12186 * eval.c (inhibit_lisp_code): Rename from
12187 inhibit_window_configuration_change_hook; move from window.c.
12189 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12190 * window.c (run_window_configuration_change_hook)
12191 (syms_of_window): Callers changed.

12211 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12214 2012-03-03 Glenn Morris <rgm@gnu.org>
12216 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12218 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12220 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12221 position past the first glyph_row that ends at ZV. (Bug#10902)
12222 (redisplay_window, next_element_from_string): Fix typos in
12224 (redisplay_window): Pass to move_it_vertically the margin in
12225 pixels, not in screen lines.
12227 2012-03-02 Glenn Morris <rgm@gnu.org>
12229 * buffer.c (buffer-list-update-hook): Doc fix.
12231 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12233 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12234 push_it before setting up the iterator for the first overlay
12235 string, even if we have an empty string loaded.
12236 (next_overlay_string): If there's an empty string on the iterator
12237 stack, pop the stack. (Bug#10903)
12239 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12241 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12242 Suggested by Stefan Monnier in
12243 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12244 * alloc.c (widen_to_Lisp_Object): New static function.
12245 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12246 and widening them to Lisp_Objects. This would work even if
12247 USE_LSB_TAG is defined and wide integers are used, which might
12248 happen in a future version of Emacs.
12250 2012-02-25 Chong Yidong <cyd@gnu.org>
12252 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12255 * xselect.c (Fx_selection_exists_p): Doc fix.

12257 before saving to clipboard manager.
12259 2012-02-24 Chong Yidong <cyd@gnu.org>
12261 * keyboard.c (process_special_events): Handle all X selection
12262 requests in kbd_buffer, not just the next one (Bug#8869).
12264 2012-02-23 Chong Yidong <cyd@gnu.org>
12266 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12267 call when setting menu-bar-lines and tool-bar-lines parameters.
12268 (unwind_create_frame_1): New helper function.

12289 when computing $valmask.
12291 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12292 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12293 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12294 It's useless in that case, and it can cause problems on hosts
12295 that allocate halves of EMACS_INT values separately.
12296 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12297 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12298 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12299 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12300 it avoids undefined behavior on hosts where shifting right by more
12301 than the word width has undefined behavior.
12303 2012-02-19 Chong Yidong <cyd@gnu.org>
12305 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12306 (Funhandled_file_name_directory, Ffile_name_as_directory)

12325 2012-02-15 Chong Yidong <cyd@gnu.org>
12327 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12328 marked as special. Also, starting docstrings with * is obsolete.

12343 2012-02-12 Chong Yidong <cyd@gnu.org>
12345 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12346 as that creates a dangerous corner case.
12348 * window.c (Fdelete_window_internal): Invalidate the mouse
12349 highlight (Bug#9904).
12351 2012-02-12 Glenn Morris <rgm@gnu.org>

12354 (Fx_get_selection_internal, Fx_disown_selection_internal)
12355 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12356 * nsselect.m (Fx_own_selection_internal)
12357 (Fx_disown_selection_internal, Fx_selection_exists_p)
12358 (Fx_selection_owner_p, Fx_get_selection_internal):
12359 Sync docs and argument specs with the xselect.c versions.
12361 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12363 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

12381 2012-02-07 Chong Yidong <cyd@gnu.org>
12383 * buffer.c (Fbuffer_local_variables)
12384 (buffer_lisp_local_variables): Handle unbound vars correctly;
12385 don't let Qunbound leak into Lisp.
12387 2012-02-07 Glenn Morris <rgm@gnu.org>
12389 * image.c (Fimagemagick_types): Doc fix.
12391 * image.c (imagemagick-render-type): Change it from a lisp object
12392 to an integer. Move the doc here from the lisp manual.
12393 Treat all values not equal to 0 the same.
12395 2012-02-06 Chong Yidong <cyd@gnu.org>
12397 * doc.c (store_function_docstring): Avoid applying docstring of

12421 * keyboard.c (adjust_point_for_property): Don't position point
12422 before BEGV. (Bug#10696)
12424 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12426 Handle overflow when computing char display width (Bug#9496).
12427 * character.c (char_width): Return EMACS_INT, not int.
12428 (char_width, c_string_width): Check for overflow when
12429 computing the width; this is possible now that individual
12430 characters can have unbounded width. Problem introduced
12431 by merge from Emacs 23 on 2012-01-19.
12433 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

12966 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
12967 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
12968 this macro definition.
12970 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
12973 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

12995 * xdisp.c (redisplay_window): If cursor row is not fully visible
12996 after recentering, and scroll-conservatively is set to a large
12997 number, scroll window by a few more lines to make the cursor fully
12998 visible and out of scroll-margin. (Bug#10105)
12999 (start_display): Don't move to the next line if the display should
13000 start at a newline that is part of a display vector or an overlay
13001 string. (Bug#10119)

13081 Otherwise, valgrind does not work on some platforms.
13082 Problem reported by Andreas Schwab in
13083 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13084 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13085 is set, removing the need for VIRT_ADDRESS_VARIES.
13086 (PURE_P): Use a more-efficient implementation that needs just one
13087 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13088 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13089 to 4 (xorl, subq, cmpq, setbe).
13090 * alloc.c (pure): Always extern now, since that's the
13091 VIRT_ADDR_VARIES behavior.
13092 (PURE_POINTER_P): Use a single comparison, not two, for
13093 consistency with the new puresize.h.
13094 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13095 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13096 Remove VIRT_ADDR_VARIES no longer needed.

13101 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13102 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13103 behave as if the cursor position were at the window margin.
13105 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13106 and the cursor position is out of bounds, behave as if the cursor
13107 position were at the window margin. (Bug#10075)
13109 2011-11-18 Chong Yidong <cyd@gnu.org>
13111 * window.c (Fwindow_combination_limit): Make first argument
13112 non-optional, since it is meaningless for live windows like the

13126 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
13127 hash values of the two rows.
13128 (copy_row_except_pointers): Preserve the used[] arrays and the
13129 hash values of the two rows. (Bug#10035)
13130 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13132 * xdisp.c (row_hash): New function, body extracted from
13133 compute_line_metrics.
13134 (compute_line_metrics): Call row_hash, instead of computing the
13137 * dispnew.c (verify_row_hash): Call row_hash for computing the
13138 hash code of a row, instead of duplicating code from xdisp.c.
13140 * dispextern.h (row_hash): Add prototype.
13142 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13144 * frame.c (delete_frame): Don't delete the terminal when the last

13169 (recombine_windows, make_parent_window, make_window)
13170 (Fsplit_window_internal, saved_window)
13171 (Fset_window_configuration, save_window_save): Rename all
13172 occurrences of window_nest to window_combination_limit.
13174 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
13176 * image.c (imagemagick_load_image): Fix typo.
13178 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13180 * xdisp.c (display_line): Move the call to
13181 highlight_trailing_whitespace before the call to
13182 compute_line_metrics, since the latter needs to see the final
13183 faces of all the glyphs to compute ROW's hash value.
13184 Fixes assertion violations in row_equal_p. (Bug#10035)
13186 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13188 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13189 just return (bug#10044).
13191 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13193 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13194 with user-defined heap size. Bump the default size of the temacs
13195 heap to 27MB, to avoid memory warning when running temacs.
13196 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13198 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13199 current_matrix and desired_matrix. (Bug#9990)
13200 (verify_row_hash) [XASSERTS]: New function.
13201 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13202 that the hash value of glyph rows is correct.

13231 2011-11-11 Johan Bockgård <bojohan@gnu.org>
13233 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
13234 avoid a crash (bug#9496).
13236 2011-11-09 Chong Yidong <cyd@gnu.org>
13238 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13245 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13247 Avoid some portability problems by eschewing 'extern inline' functions.
13248 The trivial performance wins aren't worth the portability hassles; see
13249 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13251 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13252 (window_box_width, window_box_left, window_box_left_offset)
13253 (window_box_right, window_box_right_offset): Undo previous change,
13254 by removing the "extern"s.
13255 * intervals.c (adjust_intervals_for_insertion)
13256 (adjust_intervals_for_deletion): Undo previous change,
13257 making these static again.
13258 (offset_intervals, temp_set_point_both, temp_set_point)
13259 (copy_intervals_to_string): No longer inline.
13260 * xdisp.c (window_text_bottom_y, window_box_width)

13291 (delete_all_subwindows): Rename to delete_all_child_windows.
13292 (Fdelete_other_windows_internal, Fset_window_configuration):
13293 Call delete_all_child_windows instead of delete_all_subwindows.

13297 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
13299 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
13300 This is also needed for porting to any host where GC_MARK_STACK is
13301 not GC_MAKE_GCPROS_NOOPS.
13302 (which_symbols): Use it.
13304 2011-11-07 Kenichi Handa <handa@m17n.org>
13306 * coding.c (coding_set_destination): Check coding->src_pos only
13307 when coding->src_object is a buffer (bug#9910).

13317 * xmenu.c (cleanup_widget_value_tree): New function.
13318 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13319 calling free_menubar_widget_value_tree directly (Bug#9830).
13321 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13323 Fix some portability problems with 'inline'.
13324 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13325 (window_box_width, window_box_left, window_box_left_offset)
13326 (window_box_right, window_box_right_offset): Declare extern.
13327 Otherwise, these inline functions do not conform to C99 and
13328 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13329 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13330 * intervals.c (adjust_intervals_for_insertion)
13331 (adjust_intervals_for_deletion): Now extern, because otherwise the
13332 extern inline functions 'offset_intervals' couldn't refer to it.
13333 (static_offset_intervals): Remove.
13334 (offset_intervals): Rewrite using the old contents of
13335 static_offset_intervals. The old version didn't conform to C99
13336 because an extern inline function contained a reference to an
13337 identifier with static linkage.
13339 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13341 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13358 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
13359 (Fwindow_vscroll): Doc fix.
13360 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13361 argument, since it makes no sense to pass a live window and for
13362 consistency with window-child.

13483 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
13484 past the beginning of the current glyph matrix.

13535 Not clear what it was for, and it causes various bugs. (Bug#9839)
13537 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13539 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

13559 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13561 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13562 <oslsachem@gmail.com> for helping to debug this.
13564 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

13570 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13572 (w32font_open_internal, compute_metrics):
13573 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13574 instead of calling the "wide" APIs directly.
13576 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13578 * w32.h (syms_of_w32font): Add prototype.
13580 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

13584 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13585 (Fmove_to_window_line): Doc fix.
13587 2011-10-27 Chong Yidong <cyd@gnu.org>
13589 * process.c (make_process): Set gnutls_state to NULL.
13591 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13592 non-NULL, regardless of GNUTLS_INITSTAGE.
13593 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13594 an error. Set process slots as soon as we allocate them.

13620 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13622 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13624 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13626 * keyboard.c (test_undefined): New function (bug#9751).
13627 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13629 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13631 * sysdep.c (init_sys_modes): Fix the check for the controlling
13632 terminal (Bug#6649).
13634 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13636 * dispextern.h (struct bidi_it): New member next_en_type.
13638 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13639 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13640 current character, check also for next_en_type being WEAK_EN.
13641 (bidi_resolve_weak): Don't enter the expensive loop if the current
13642 position is before next_en_pos. Record the bidi type of the first
13643 non-ET, non-BN character we find, in addition to its position.
13644 (bidi_level_of_next_char): Invalidate next_en_type when
13645 next_en_pos is over-stepped.
13647 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13649 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13650 * editfns.c: Rewrite current-time-zone so that it invokes
13651 the equivalent of (format-time-string "%Z") to get the time zone name.
13652 This fixes a bug when the time zone name contains characters that
13653 need converting from the system time locale to Emacs internal format.
13654 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13655 that patch fixed format-time-string to do the conversion, but
13656 I forgot to fix current-time-zone.
13657 (format_time_string): New function, containing most of
13658 what Fformat_time_string used to contain.
13659 (Fformat_time_string): Rewrite in terms of format_time_string.
13660 This doesn't change this function's behavior.
13661 (current-time-zone): Rewrite to use format_time_string.
13662 This fixes the bug reported by Michael Schierl in
13663 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13664 Jason Rumney's 2007-06-07 change worked around this bug, but
13666 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13668 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13670 * xdisp.c (start_display): If the character at POS is displayed
13671 via a display vector, reset IT->current.dpvec_index to zero.
13672 (try_window_reusing_current_matrix): If a line ends in a display
13673 vector or the next line starts in a display vector, continue
13674 redrawing the window even though the character position of
13675 start_row was reached.
13678 2011-10-18 Chong Yidong <cyd@gnu.org>
13680 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13681 with nobreak-char-display too.
13683 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13685 Fix part 3 of bug#9771.
13686 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13687 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13688 non-neutral characters if the current character is a paragraph
13689 separator (a.k.a. Newline). This avoids running the same
13690 expensive loop twice, once when we consume the preceding newline
13691 and the other time when the line actually needs to be displayed.
13692 Avoid the loop when we see neutrals on the base embedding level
13693 following a character whose directionality is the same as the
13694 paragraph's. This avoids running the expensive loop when a line
13695 ends in a long sequence of neutrals, like control characters.
13696 Add assertion against STRONG_AL type. Slightly rearrange code
13697 that determines the type of a neutral given the first non-neutral
13699 (bidi_level_of_next_char): Set next_en_pos to zero when
13700 invalidating its info.
13702 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13704 * xdisp.c (push_display_prop): Determine whether to record string
13705 or buffer position by IT->string, not by IT->method. Allow
13706 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13707 (move_it_vertically_backward): Don't look for character position
13708 immediately after the newline when in a continuation line.
13711 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13713 * window.c (coordinates_in_window): Rewrite and delabelize
13714 vertical border check. (Bug#5357) (Bug#9618)
13716 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13718 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13719 errors in XSetWindowBorder (bug#9310).
13721 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13723 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13724 avoid crash when xmalloc overrun checking is enabled.
13726 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13728 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13729 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13730 cursor motion with <left> and <right> arrow keys.
13732 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13733 some callers set that themselves.
13735 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13737 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13738 display string and the previous row comes from the same string and
13739 is empty. (Bug#9739) (Bug#9738)
13741 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13743 * doc.c (get_doc_string): Encode file name (bug#9735).
13745 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13747 * bidi.c (bidi_level_of_next_char):
13748 * xdisp.c (get_visually_first_element): Remove old incorrect
13749 comments regarding the Unicode Line Separator character.
13751 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13753 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13755 * alloc.c (Fgc_status): Do not access beyond zombies array
13756 boundary if nzombies > MAX_ZOMBIES.
13757 * alloc.c (dump_zombies): Add missing format specifier.
13759 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13761 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13762 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13764 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13765 Some packages use them to denote characters with modifiers.
13767 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13769 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13770 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13771 matching a pp-number. Rename parameter var to var1.
13773 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13775 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13777 2011-10-08 Glenn Morris <rgm@gnu.org>
13779 * callint.c (Fcall_interactively): Give a more explicit error for the
13780 'c' case with a non-character input. (Bug#8479)
13782 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13784 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13786 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13787 lines that are hscrolled on the left.

13790 presence of header-line. (Bug#4426)
13792 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13794 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13795 Don't advertise functionality which we discourage or doesn't work.
13797 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13799 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13800 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13801 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13802 this makes Emacs dump core during garbage collection on rare
13803 occasions. sizeof is obviously inferior to offsetof here, so
13804 stick with offsetof.
13805 (GC_POINTER_ALIGNMENT): New macro.
13806 (mark_memory): Omit 3rd (offset) arg; caller changed.
13807 Don't assume EMACS_INT alignment is the same as pointer alignment.
13809 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13811 * keyboard.c (read_key_sequence_remapped): New var.
13812 (read_key_sequence): Compute remapping in the right buffer.
13813 (command_loop_1): Use read_key_sequence's remapping directly.
13815 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13817 * dired.c (file_name_completion): Don't expand file name.
13818 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13819 before checking file name handler.
13821 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13822 they've been requested explicitly (bug#9591).
13824 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13826 * keymap.c (Fsingle_key_description): Use make_specified_string
13827 instead of build_string to build string from push_key_description.
13830 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13832 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13833 This fixes a Y2038 bug on 64-bit hosts.
13834 * buffer.c (reset_buffer):
13835 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13836 (Fclear_buffer_auto_save_failure):
13837 Use 0, not -1, to represent an unset failure time, since time_t
13838 might not be signed.
13840 Remove dependency on glibc malloc internals.
13841 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13842 Move back here from lisp.h, but with their new implementations.
13843 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13844 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13845 * charset.c (charset_table_init): New static var.
13846 (syms_of_charset): Use it instead of xmalloc. This removes a
13847 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13848 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13849 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13850 Move back to alloc.c.
13851 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13852 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13854 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13856 * nsterm.m (windowDidResize): Call x_set_window_size only when
13857 ns_in_resize is true. Otherwise set pixelwidth/height and
13858 call change_frame_size (Bug#9628).
13860 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13862 Port --enable-checking=all to Fedora 14 x86-64.
13863 * charset.c (syms_of_charset): Also account for glibc malloc's
13864 internal overhead when calculating the initial malloc maximum.
13866 Port --enable-checking=all to Fedora 14 x86.
13867 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13869 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13870 (overrun_check_realloc, overrun_check_free):
13871 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13872 That way, xmalloc returns a properly-aligned pointer even if
13873 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13874 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13875 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13876 into account when calculating the initial malloc maximum.
13877 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13878 Move here from alloc.c, so that charset.c can use it too.
13879 Properly align; the old code wasn't right for common 32-bit hosts
13880 when configured with --enable-checking=all.
13881 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13882 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13884 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13886 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13889 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13891 * xdisp.c (compute_display_string_end): If there's no display
13892 string at CHARPOS, return -1.
13894 * bidi.c (bidi_fetch_char): When compute_display_string_end
13895 returns a negative value, treat the character as a normal
13896 character not covered by a display string. (Bug#9624)
13898 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13900 * lread.c (Fread_from_string): Fix typo in docstring.
13902 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13904 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13905 newline, reseat the iterator instead of bidi-iterating there one
13906 character at a time. (Bug#9610)
13907 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13908 TO_CHARPOS if the bidi iterator is at base embedding level.
13910 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13912 * lread.c (readevalloop): Use correct code for NBSP.
13913 (read1): Likewise. (Bug#9608)
13915 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13917 * dbusbind.c (Fdbus_register_signal): When service is not
13918 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13920 2011-09-25 Glenn Morris <rgm@gnu.org>
13922 * buffer.c (truncate-lines): Doc fix.
13924 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13926 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13927 (Fset_window_next_buffers): Doc fix.
13929 2011-09-24 Glenn Morris <rgm@gnu.org>
13931 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13933 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13935 Fix minor problems found by static checking.
13936 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13937 * indent.c (Fvertical_motion): Fix == vs = typo.
13939 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13941 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13942 Default value is now t. Doc fix.
13944 * indent.c (Fvertical_motion): Compute and apply the overshoot
13945 logic when moving up, not only when moving down. Fix the
13946 confusing name and values of the it_overshoot_expected variable;
13947 logic changes accordingly. (Bug#9254) (Bug#9549)
13949 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13950 CHARPOS is covered by a display string which includes newlines.
13951 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13952 is covered by a display string with embedded newlines.
13954 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13956 * dbusbind.c (Fdbus_register_signal): Add match rule to
13957 Vdbus_registered_objects_table. (Bug#9581)
13958 (Fdbus_register_method, Vdbus_registered_objects_table):
13961 2011-09-24 Jim Meyering <meyering@redhat.com>
13963 do not ignore write error for any output size
13964 The previous change was incomplete.
13965 While it makes emacs --batch detect the vast majority of stdout
13966 write failures, errors were still ignored whenever the output size is
13967 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13968 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13969 && echo FAIL: ignored write error
13970 FAIL: ignored write error
13971 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13972 && echo FAIL: ignored write error
13973 FAIL: ignored write error
13974 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13976 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13978 * emacs.c (Fkill_emacs): In noninteractive mode exit
13979 non-successfully if a write error occurred on stdout. (Bug#9574)
13981 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13983 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13986 * dispextern.h (struct it): Update the comment documenting what
13989 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13991 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13992 a display string, extend search for cursor position to end of row.
13993 (find_row_edges): If the row ends in a newline from a display
13994 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13995 Handle the case of a display string with multiple newlines.
13996 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13997 non-empty line. Fixes confusing cursor motion with arrow keys at
13998 the beginning of a line that starts with whitespace.
14000 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14002 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14005 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14007 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14008 boolean (Bug#9154).
14010 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14012 * xdisp.c (display_line): Record maximum and minimum buffer
14013 positions even if no glyphs were produced (e.g., by a zero-width
14014 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14015 buffer positions that will be removed from the glyph row because
14017 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14018 column is beyond frame width: don't subtract 1 "pixel" when
14019 computing width of the stretch.
14020 (reseat_at_next_visible_line_start): Undo the change made on
14021 2011-09-17 that saved paragraph information and restored it after
14022 the call to `reseat'. (Bug#9545)
14024 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14026 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14027 and turn window cursor on if cleared (Bug#9415).
14029 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14031 * search.c (boyer_moore): Take unibyte characters from pattern
14032 literally. (Bug#9458)
14034 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14036 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14038 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14040 Fix minor problem found by static checking.
14041 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14042 initialized, to pacify gcc -Wuninitialized.
14044 * fileio.c: Report proper errno when syscall falls.
14045 (Finsert_file_contents): Save and restore errno,
14046 so that report_file_error outputs the correct diagnostic.
14047 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14049 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14051 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14053 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14055 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14056 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14058 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14060 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14061 about the current paragraph and restore it after the call to reseat.
14063 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14064 (bidi_find_paragraph_start): Search back for paragraph beginning
14065 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14066 (bidi_move_to_visually_next): Only trigger paragraph-related
14067 computations when the last character is a newline or at EOB, not
14068 just any NEUTRAL_B. (Bug#9470)
14070 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14071 truncated lines if point is covered by a display string. (Bug#9524)
14073 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14075 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14076 (cons_to_x_long): New function.
14077 (lisp_data_to_selection_data): Use it. Correct the test for
14078 short-versus-long data; it was negated. Break out of vector
14079 loop, for efficiency, when a long datum is discovered.
14081 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14083 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14085 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14087 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14088 GCC PR/17406) by declaring this function with external scope.
14090 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14092 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14093 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14095 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14097 * editfns.c (Fformat): Correctly handle text properties on "%%".

14105 * xdisp.c (get_next_display_element)
14106 (fill_composite_glyph_string): Add comments about special meaning
14107 of TAB characters in a composition.
14109 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14111 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14112 This occurs when processing a multibyte format.
14113 Problem reported by Wolfgang Jenker.
14115 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14117 * xdisp.c (try_cursor_movement): Only check for exact match if
14118 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14120 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14122 Remove unused external symbols.
14123 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14124 * xdisp.c (calc_pixel_width_or_height): Now static.
14125 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14126 * indent.c (check_display_width):
14127 * w32term.c: Fix comment to match code.
14128 * xterm.c, xterm.h (x_catching_errors): Remove.
14130 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14132 * xselect.c: Use signed conversions more consistently (Bug#9498).
14133 (selection_data_to_lisp_data): Assume incoming selection data are
14134 signed integers, not unsigned. This is to be consistent with
14135 outgoing selection data, which was modified to use signed integers
14136 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14137 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14138 expects long, not unsigned long.
14140 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14142 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14143 computation of loop end. Reported by Johan Bockgård
14146 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14148 * frame.c (Fother_visible_frames_p): Function deleted.
14150 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14152 * indent.c (compute_motion): Process display vector front to back
14153 rather than the other way around. (Bug#2496)
14155 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14157 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14159 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14161 * minibuf.c (Fread_from_minibuffer): Doc fix.
14163 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14165 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14166 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14168 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14170 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14171 value for non-existent files.
14173 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14175 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14176 set its "size" to -1. This will set the modtime_size field of
14177 the corresponding buffer to -1, which is what
14178 verify-visited-file-modtime expects for files that do not exist.
14181 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14183 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14185 * lisp.h: ... from here. push_key_description is no longer
14186 defined in keyboard.c, so its declaration should not be in
14187 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14188 logically belongs with push_key_description.
14190 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14192 * buffer.h: Include <sys/types.h> instead of <time.h>.
14193 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14194 Problem reported by Herbert J. Skuhra.
14196 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14198 * xml.c (parse_region): Make the parsing work for
14199 non-comment-starting XML files again (bug#9144).
14201 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14203 * image.c (gif_load): Fix calculation of bottom and right corner.
14206 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14208 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14209 redisplay in small windows.
14211 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14213 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14215 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14217 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14218 Operate on live windows only.
14220 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14222 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14224 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14226 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14227 only under bidi iteration.
14229 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14231 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14233 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14235 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14236 Without this fix, the command to link temacs failed due to an
14237 undefined symbol __builtin_isnan. This is because
14238 /usr/include/iso/math_c99.h #defines isnan(x) to
14239 __builtin_isnan(x), but the bundled gcc, which identifies itself
14240 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14242 * floatfns.c (isnan): #undef, and then #define to a clone of
14244 (Fisnan): Always define, since it's always available now.
14245 (syms_of_floatfns): Always define isnan at the Lisp level.
14247 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14249 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14251 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14253 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14254 The previous code assumed that file offsets (off_t values) fit in
14255 EMACS_INT variables, which is not true on typical 32-bit hosts.
14256 The code messed up by falsely reporting buffer overflow in cases
14257 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14258 when "big" contains more than 2**29 bytes, even though this
14259 inserts just one byte and does not overflow the buffer.
14260 (Finsert_file_contents): Store file offsets as off_t
14261 values, not as EMACS_INT values. Check for overflow when
14262 converting between EMACS_INT and off_t. When checking for
14263 buffer overflow or for overlap, take the offsets into account.
14264 Don't use EMACS_INT for small values where int suffices.
14265 When checking for overlap, fix a typo: ZV was used where
14266 ZV_BYTE was intended.
14267 (Fwrite_region): Don't assume off_t fits into 'long'.
14268 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14270 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14272 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14274 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14276 sprintf-related integer and memory overflow issues (Bug#9412).
14278 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14279 (esprintf, exprintf, evxprintf): New functions.
14280 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14281 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14282 (modify_event_symbol): Do not assume that the length of
14283 name_alist_or_stem is safe to alloca and fits in int.
14284 (Fexecute_extended_command): Likewise for function name and binding.
14285 (Frecursion_depth): Wrap around reliably on integer overflow.
14286 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14287 since some callers pass EMACS_INT values.
14288 (Fsingle_key_description): Don't crash if symbol name contains more
14289 than MAX_ALLOCA bytes.
14290 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14291 (get_minibuffer): Arg is now EMACS_INT, not int.
14292 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14293 (esprintf, exprintf, evxprintf): New decls.
14294 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14296 * dbusbind.c (signature_cat): New function.
14297 (xd_signature, Fdbus_register_signal):
14298 Do not overrun buffer; instead, report string overflow.
14300 * dispnew.c (add_window_display_history): Don't overrun buffer.
14301 Truncate instead; this is OK since it's just a log.
14303 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14304 even if the time zone offset is outlandishly large.
14305 Don't mishandle offset == INT_MIN.
14307 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14308 when creating daemon; the previous buffer-overflow check was incorrect.
14310 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14311 which has the guts of the old verror function.
14313 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14314 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14316 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14317 (font_unparse_xlfd): Don't blindly alloca long strings.
14318 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14319 fits in int, when using sprintf. Use single snprintf to count
14320 length of string rather than counting it via multiple sprintfs;
14321 that's simpler and more reliable.
14322 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14323 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14324 sprintf, in case result does not fit in int.
14326 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14327 (fontset_from_font): Print it.
14329 * frame.c (tty_frame_count): Now printmax_t, not int.
14330 (make_terminal_frame, set_term_frame_name): Print it.
14331 (x_report_frame_params): In X, window IDs are unsigned long,
14332 not signed long, so print them as unsigned.
14333 (validate_x_resource_name): Check for implausibly long names,
14334 and don't assume name length fits in 'int'.
14335 (x_get_resource_string): Don't blindly alloca invocation name;
14336 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14339 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14340 (xg_check_special_colors, xg_set_geometry):
14341 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14343 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14344 Use esprintf, not sprintf, in case result does not fit in int.
14346 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14347 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14348 it as a large positive number.
14349 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14350 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14352 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14353 in case result does not fit in int.
14355 * print.c (float_to_string): Detect width overflow more reliably.
14356 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14357 buffer overrun. Don't assume list length fits in 'int'. Treat
14358 print length of 0 as 0, not as infinity; to be consistent with other
14359 uses of print length in this function. Don't overflow print length
14360 index. Don't assume hash table size fits in 'long', or that
14361 vectorlike size fits in 'unsigned long'.
14363 * process.c (make_process): Use printmax_t, not int, to format
14364 process-name gensyms.
14366 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14368 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14369 to avoid potential buffer overrun.
14371 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14372 if X resource line is longer than 512 bytes.
14374 * xfns.c (x_window): Make sprintf buffer a bit bigger
14375 to avoid potential buffer overrun.
14377 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14379 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14381 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14383 Integer overflow fixes for scrolling, etc.
14384 Without these, Emacs silently mishandles large integers sometimes.
14385 For example, "C-u 4294967297 M-x recenter" was treated as if
14386 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14388 * xdisp.c (try_window_id): Check Emacs fixnum range before
14389 converting to 'int'.
14391 * window.c (window_scroll_line_based, Frecenter):
14392 Check that an Emacs fixnum is in range before assigning it to 'int'.
14393 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14394 values converted from Emacs fixnums.
14395 (Frecenter): Don't wrap around a line count if it is out of 'int'
14396 range; instead, treat it as an extreme value.
14397 (Fset_window_configuration, compare_window_configurations):
14398 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14400 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14401 that can exceed INT_MAX. Check that EMACS_INT value is in range
14402 before assigning it to the (possibly-narrower) index.
14403 (match_limit): Don't assume that a fixnum can fit in 'int'.
14405 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14408 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14409 (Fvertical_motion): Don't wrap around LINES values that don't fit
14410 in 'int'. Instead, treat them as extreme values. This is good
14411 enough for windows, which can't have more than INT_MAX lines anyway.
14413 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14415 * Require libxml/parser.h to avoid compilation warning.
14417 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14419 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14420 since this reportedly can destroy thread storage.
14422 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14424 * syntax.c (find_defun_start): Update all cache variables if
14425 exiting early (Bug#9401).
14427 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14429 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14431 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14432 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14433 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14435 * term.c (tty_append_glyph): New function.
14436 (produce_stretch_glyph): Static function and its prototype deleted.
14438 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14441 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14443 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14444 when checking :margin (Bug#9390).
14445 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14446 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14447 so that the name doesn't mislead. All uses changed.
14449 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14451 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14454 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14456 * xdisp.c (move_it_to): Don't bail out early when reaching
14457 position beyond to_charpos, if we are scanning backwards.
14458 (move_it_vertically_backward): When DY == 0, make sure we get to
14459 the first character in the line after the newline.
14461 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14463 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14464 (ccl_driver): Do not generate an out-of-range pointer.
14465 (Fccl_execute_on_string): Remove unnecessary check for
14466 integer overflow, noted by Stefan Monnier in
14467 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14468 Remove a FIXME that didn't need fixing.
14469 Simplify the newly-introduced buffer reallocation code.
14471 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14473 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14475 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14477 Integer and memory overflow issues (Bug#9196).
14479 * doc.c (get_doc_string): Rework so that
14480 get_doc_string_buffer_size is the actual buffer size, rather than
14481 being 1 less than the actual buffer size; this makes xpalloc more
14484 * image.c (x_allocate_bitmap_record, cache_image):
14485 * xselect.c (Fx_register_dnd_atom):
14486 Simplify previous changes by using xpalloc.
14488 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14489 since either will do and ptrdiff_t is convenient with xpalloc.
14491 * charset.c (charset_table_size)
14492 (struct charset_sort_data.priority): Now ptrdiff_t.
14493 (charset_compare): Don't overflow if priorities differ greatly.
14494 (Fsort_charsets): Don't assume list length fits in int.
14495 Check for size-calculation overflow when allocating sort data.
14496 (syms_of_charset): Allocate an initial charset table that is
14497 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14499 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14501 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14502 The actual value is always <= INT_MAX, and leaving it unsigned made
14503 overflow checking harder.
14505 * dispextern.h (struct glyph_matrix.rows_allocated)
14506 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14507 with xpalloc. The values are still always <= INT_MAX.
14509 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14511 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14512 (SAFE_NALLOCA): New macro.
14514 * region-cache.c (struct boundary.pos, find_cache_boundary)
14515 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14516 (set_cache_region, invalidate_region_cache)
14517 (revalidate_region_cache, know_region_cache, region_cache_forward)
14518 (region_cache_backward, pp_cache):
14519 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14520 so that ptrdiff_t * can be passed to xpalloc.
14521 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14522 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14523 (pp_cache): Don't assume cache_len fits in int.
14524 * region-cache.h: Adjust extern decls to match.
14526 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14527 EMACS_INT, since either will do, for xpalloc.
14529 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14530 (xnmalloc, xnrealloc, xpalloc): New functions.
14532 * bidi.c (bidi_shelve_header_size): New constant.
14533 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14534 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14536 * bidi.c (bidi_cache_shrink):
14537 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14539 Don't update size of array until after memory allocation succeeds,
14540 because xmalloc/xrealloc may not return.
14541 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14542 now that we have proper integer overflow checking.
14543 (record_overlay_string, overlay_strings): Catch overflows when
14544 calculating size of overlay_str_buf.
14546 * callproc.c (Fcall_process): Check for size overflow when
14547 calculating size of args2.
14548 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14549 Normally we prefer signed values, but sticking with ptrdiff_t would
14550 require adding more-complicated checks.
14552 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14553 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14554 Redo buffer-overflow calculations to avoid integer overflow.
14555 Add a FIXME comment where memory seems to be over-allocated.
14557 * character.c (Fstring): Check for size-calculation overflow.
14559 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14560 unnecessary integer overflow. Check for size overflow.
14561 (encode_coding_object): Don't update size until xmalloc succeeds.
14563 * composite.c (get_composition_id): Check for overflow in glyph
14564 length calculations.
14566 Integer and memory overflow fixes for display code.
14567 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14568 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14569 (scrolling_window): Check for overflow in size calculations.
14570 (line_draw_cost, realloc_glyph_pool, add_row_entry):
14571 Don't assume glyph table len fits in int.

14573 (row_table_size): Now ptrdiff_t, not int.
14574 (scrolling_window): Avoid overflow in size calculations.
14575 Don't update size until allocation succeeds.
14576 * fns.c (concat): Check for overflow in size calculations.
14577 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14578 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
14579 (NEXT_ALMOST_PRIME_LIMIT): New constant.
14581 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14582 (get_doc_string): Check for size calculation overflow.
14583 Don't update size until allocation succeeds.
14584 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14585 EMACS_INT, where ptrdiff_t will do.
14586 (Fsubstitute_command_keys): Check for string overflow.
14588 * editfns.c (set_time_zone_rule): Don't assume environment length
14590 (message_length): Now ptrdiff_t, not int.
14591 (Fmessage_box): Don't update size until allocation succeeds.
14592 Don't assume message length fits in int.
14593 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14595 * emacs.c (main): Do not reallocate argv, since there is a null at
14596 the end that can be overwritten, and this way there's no need to
14597 worry about size-calculation overflow.
14598 (sort_args): Check for size-calculation overflow.
14600 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14602 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14604 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14605 (x_set_scroll_bar_width, x_figure_window_size):
14606 Check for integer overflow.
14607 (x_set_alpha): Do not assume XINT fits in int.
14609 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14610 This is for the members text_lines, text_cols, total_lines, total_cols,
14611 where the system imposes an 'int' limit.
14613 * fringe.c (Fdefine_fringe_bitmap):
14614 Don't update size until alloc works.
14616 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14617 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14619 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14620 Check for size-calculation overflow.
14621 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14622 do, as we prefer signed integers.
14623 (id_to_widget.max_size, id_to_widget.used)
14624 (xg_store_widget_in_map, xg_remove_widget_from_map)
14625 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14626 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14627 Use and return ptrdiff_t, not int.
14628 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14629 * gtkutil.h: Change prototypes to match the above.
14631 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14632 are duplicate now that they've been promoted to lisp.h.
14633 (x_allocate_bitmap_record, x_alloc_image_color)
14634 (make_image_cache, cache_image, xpm_load):
14635 Don't update size until alloc is done.
14636 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

14639 (ct_colors_allocated_max): New constant.
14640 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
14643 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
14644 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
14645 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
14646 Use ptrdiff_t, not int, to count maps.
14647 (read_char_minibuf_menu_prompt): Check for overflow in size
14648 calculations. Don't update size until allocation succeeds.
14649 Redo calculations to avoid overflow.
14650 * keyboard.h: Change prototypes to match the above.
14652 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14654 (current_minor_maps): Check for size calculation overflow.
14655 * keymap.h: Change prototypes to match the above.
14657 * lread.c (read1, init_obarray): Don't update size until alloc done.
14659 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
14660 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

14670 * region-cache.c (move_cache_gap): Check for size calculation overflow.
14672 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
14673 overflow. Don't bother calling xmalloc when xrealloc will do.

14676 (Fset_match_data): Don't assume list lengths fit in 'int'.
14678 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14679 for command line length. Do not attempt to address one before the
14680 beginning of an array, as that's not portable.
14682 * term.c (max_frame_lines): Remove; unused.
14683 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14685 (encode_terminal_code, calculate_costs): Check for size
14686 calculation overflow.

14704 Use ptrdiff_t, not int, for sizes.
14705 (store_mode_line_noprop_char): Don't update size until alloc done.
14707 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
14708 Use ptrdiff_t, not int, for sizes.
14709 (Finternal_make_lisp_face, cache_face):
14710 Check for size calculation overflow.
14711 (cache_face): Treat size calculation overflows as if they were
14712 memory exhaustion (the usual treatment), rather than aborting.
14714 * xfns.c (x_encode_text, x_set_name_internal)
14715 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14716 sizes, since they can exceed INT_MAX in size. Check for size
14717 calculation overflow.
14719 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14720 (xg_select): Check for size calculation overflow.
14721 Don't update size until alloc done.
14723 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14724 as sprintf is limited to int lengths.
14726 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14727 (X_LONG_MIN): New macros.
14728 Use them to make the following changes clearer.
14729 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14730 This change doesn't affect the value now, but it may help remind
14731 future maintainers not to raise the value too much later.
14732 (SELECTION_QUANTUM): Remove, replacing with ...
14733 (selection_quantum): ... new function, which avoids overflow.
14735 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14736 assumption that selection length fits in 'int'.
14737 (x_reply_selection_request, x_handle_selection_request)
14738 (x_get_window_property, receive_incremental_selection)
14739 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14740 (lisp_data_to_selection_data, clean_local_selection_data):
14741 Use ptrdiff_t, not int, to record length of selection.
14742 (x_reply_selection_request, x_get_window_property)
14743 (receive_incremental_selection, x_property_data_to_lisp):
14744 Redo calculations to avoid overflow.
14745 (x_reply_selection_request): When sending hint, ceiling it at
14746 X_LONG_MAX rather than relying on wraparound overflow to send
14748 (x_get_window_property, receive_incremental_selection)
14749 (lisp_data_to_selection_data, x_property_data_to_lisp):
14750 Check for size-calculation overflow.
14751 (x_get_window_property, receive_incremental_selection)
14752 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14753 Don't store size until memory allocation succeeds.
14754 (x_get_window_property): Plug memory leak on memory exhaustion.
14755 Don't double-block input; malloc is safe here. Don't assume 2**34
14756 - 4 fits in unsigned long. Add an xassert to check
14757 XGetWindowProperty overflow. Be more careful about overflow
14758 calculations, and distinguish size from memory overflow better.
14759 (receive_incremental_selection): When tracing, don't assume
14760 unsigned int is less than INT_MAX.
14761 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14762 harmful) conversions of unsigned short to int.
14763 (lisp_data_to_selection_data): Don't assume that integers
14764 in the range -65535 through -1 fit in an X unsigned short.
14765 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14766 result parameters unless successful. Rely on cons_to_unsigned
14767 to report problems with elements; the old code wasn't right anyway.
14768 (x_check_property_data): Check for int overflow; we cannot use
14769 a wider type due to X limits.
14770 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14772 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
14774 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
14775 (x_term_init): Check for size calculation overflow.
14776 (x_color_cells): Don't store size until memory allocation succeeds.
14777 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
14778 Don't assume alloca size is less than MAX_ALLOCA.
14779 (x_term_init): Don't assume length fits in int (sprintf is limited
14782 Use ptrdiff_t for composition IDs.
14783 * character.c (lisp_string_width):
14784 * composite.c (composition_table_size, n_compositions)
14785 (get_composition_id, composition_gstring_from_id):
14786 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):

14800 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
14801 * image.c (xpm_get_color_table_h):
14802 * lisp.h (hash_lookup, hash_put):
14803 * minibuf.c (Ftest_completion):
14804 Use ptrdiff_t for hash table indexes, not int (which is too
14805 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14806 32-bit --with-wide-int hosts).
14808 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14809 Add a FIXME comment about memory leaks.
14810 (syms_of_charset): Don't assume xmalloc returns.
14812 Don't assume that stated character widths fit in int.
14813 * character.c (Fchar_width, c_string_width, lisp_string_width):
14814 * character.h (CHAR_WIDTH):
14815 * indent.c (MULTIBYTE_BYTES_WIDTH):
14816 Use sanitize_char_width to avoid undefined and/or bad behavior
14817 with outlandish widths.
14818 * character.h (sanitize_tab_width): Rename from sanitize_width,
14819 now that we have two such functions. All uses changed.
14820 (sanitize_char_width): New inline function.
14822 Don't assume that tab-width fits in int.
14823 * character.h (sanitize_width): New inline function.
14824 (SANE_TAB_WIDTH): New macro.
14825 (ASCII_CHAR_WIDTH): Use it.
14826 * indent.c (sane_tab_width): Remove. All uses replaced by
14827 SANE_TAB_WIDTH (current_buffer).
14828 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
14830 * fileio.c: Integer overflow issues with file modes.
14831 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14833 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
14834 Remove unreachable code.
14835 (read_hex, load_charset_map_from_file): Check for integer overflow.
14837 * xterm.c: Don't go over XClientMessageEvent limit.
14838 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14839 (x_send_scroll_bar_event): Likewise. Check that the size does not
14840 exceed limits imposed by XClientMessageEvent, as well as the usual
14841 ptrdiff_t and size_t limits.
14843 * keyboard.c: Overflow, signedness and related fixes.
14844 (make_lispy_movement): Use same integer type in forward decl
14845 that is used in the definition.
14846 (read_key_sequence, keyremap_step):
14847 Change bufsize argument back to int, undoing my 2011-03-30 change.
14848 We prefer signed types, and int is wide enough here.
14849 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14850 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14851 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14852 length, not size_t. Use ptrdiff_t for index, not int.
14853 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14854 possibility of integer overflow.
14856 Overflow, signedness and related fixes for images.
14858 * dispextern.h (struct it.stack[0].u.image.image_id)
14859 (struct_it.image_id, struct image.id, struct image_cache.size)
14860 (struct image_cache.used, struct image_cache.ref_count):

14866 * xdisp.c (calc_pixel_width_or_height):
14867 * xfns.c (image_cache_refcount):
14868 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14869 on typical 64-bit hosts.

14875 when the callers expect that.
14876 (image_ascent): Redo ascent calculation to avoid int overflow.
14877 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14878 (lookup_image): Remove unnecessary tests.
14879 (xbm_image_p): Locals are now of int, not EMACS_INT,
14880 since parse_image_check makes sure they fit into int.
14881 (png_load, gif_load, svg_load_image):
14882 Prefer int to unsigned where either will do.
14883 (tiff_handler): New function, combining the cores of the
14884 old tiff_error_handler and tiff_warning_handler.
14885 This function is rewritten to use vsnprintf and thereby avoid
14886 stack buffer overflows. It uses only the features of vsnprintf
14887 that are common to both POSIX and native Microsoft.
14888 (tiff_error_handler, tiff_warning_handler): Use it.
14889 (tiff_load, gif_load, imagemagick_load_image):
14890 Don't assume :index value fits in 'int'.
14891 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14892 (imagemagick_load_image): Check that crop parameters fit into
14893 the integer types that MagickCropImage accepts. Don't assume
14894 Vimagemagick_render_type has a nonnegative value. Don't assume
14895 size_t fits in 'long'.
14896 (gs_load): Use printmax_t to print the widest integers possible.
14897 Check for integer overflow when computing image height and width.
14899 2011-08-26 Eli Zaretskii <eliz@gnu.org>
14901 * xdisp.c (redisplay_window): Don't force window start if point
14902 will be invisible in the resulting window. (Bug#9324)

14906 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
14907 the display spec is of the form `(space ...)'.
14908 (handle_display_spec): Return the value returned by
14909 handle_single_display_spec, not just 1 or zero.
14910 (handle_single_display_spec): If the display spec is of the form
14911 `(space ...)', and specifies display in the text area, return 2
14913 (try_cursor_movement): Check for the need to scroll more
14914 accurately, and prefer exact match for point under bidi.
14915 Don't advance `row' beyond the last row of the window.
14917 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14918 into disp_prop; all users changed.
14920 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
14921 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
14922 for the text covered by the display property.
14924 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
14926 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

14932 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14933 buffers, return left-to-right.
14934 (set_cursor_from_row): Consider candidate row a win if its glyph
14935 represents a newline and point is on that newline. Fixes cursor
14936 positioning on the newline at EOL of R2L text within L2R
14937 paragraph, and vice versa.
14938 (try_cursor_movement): Check continued rows, in addition to
14939 continuation rows. Fixes unwarranted scroll when point enters a
14940 continued line of R2L text within an L2R paragraph, or vice versa.
14941 (cursor_row_p): Consider the case of point being equal to
14942 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14943 from the end of a short line to the beginning of a continued line
14944 of R2L text within L2R paragraph.
14945 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
14946 composed characters.
14948 * bidi.c (bidi_check_type): Use xassert.

14957 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
14959 * nsfont.m (ns_otf_to_script): Fix typo.
14961 2011-08-22 Kenichi Handa <handa@m17n.org>
14963 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14964 extra slot even if the purpose is char-code-property-table.
14966 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14968 * xdisp.c (redisplay_window): When computing centering_position,
14969 account for the height of the header line. (Bug#8874)
14971 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14972 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14973 candidate is selected by the mouse, and that candidate has a
14974 composed character under the mouse.
14976 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14977 coordinates reported by pos-visible-in-window-p for a composed
14978 character in column zero.
14980 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14982 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14984 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14986 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14987 consider it a hit if to_charpos is anywhere in the range of the
14988 composed buffer positions.
14990 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14992 * image.c (gif_load): Don't assume that each subimage has the same
14993 dimensions as the base image. Handle disposal method that is
14994 "undefined" by the gif spec (Bug#9335).
14996 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14998 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
14999 (Fcondition_case): Document `debug' symbol in error handler.
15001 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15003 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15004 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15005 from an Org mode buffer to a Speedbar frame.
15007 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15008 a composition, take its buffer position from IT->cmp_it.charpos.
15009 Fixes cursor positioning at the beginning of a line that begins
15010 with a composed character.
15012 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15014 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15015 character bidirectional type, use STRONG_L instead. Fixes crashes
15016 in a buffer produced by `describe-categories'.
15018 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15019 members before the level stack, so they would be saved and
15020 restored when copying iterator state. Fixes incorrect reordering
15021 around TABs covered by display properties.
15023 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15025 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
15027 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
15029 * eval.c (internal_condition_case, internal_condition_case_1)
15030 (internal_condition_case_2, internal_condition_case_n):
15031 Remove unnecessary aborts (Bug#9081).
15033 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15035 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15036 has no `load' handler, try opening the file locally. (Bug#9311)
15038 2011-08-16 Ken Brown <kbrown@cornell.edu>
15040 * gmalloc.c: Expand comment.
15042 2011-08-16 Eli Zaretskii <eliz@gnu.org>
15044 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15045 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15047 2011-08-16 Ken Brown <kbrown@cornell.edu>
15049 Fix memory allocation problems in Cygwin build (Bug#9273).
15051 * unexcw.c ( __malloc_initialized): Declare external variable.
15052 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15054 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15056 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
15058 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
15059 in the static heap.
15060 [CYGWIN] (special_realloc): New function.
15061 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

15077 * chartab.c: Improve commentary for the uniprop_table API.
15079 * bidi.c (bidi_paragraph_init): Support zero value of
15080 bidi_ignore_explicit_marks_for_paragraph_level.
15081 (bidi_initialize): Use uniprop_table instead of including
15082 biditype.h and bidimirror.h.
15084 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
15085 coordinates of the iterator when restoring from ppos_it.
15088 2011-08-14 Kenichi Handa <handa@m17n.org>
15090 * process.c (create_process): Call setup_process_coding_systems
15091 after the pid of the process is set to -1 (Bug#8162).
15093 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15095 * xdisp.c (move_it_in_display_line_to): Don't invoke
15096 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15097 ppos_it. Fixes vertical cursor motion when line beginning is
15098 covered by an image. (Bug#9296)
15100 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15102 * nsterm.h (ns_run_ascript): Declare.
15103 (NSAPP_DATA2_RUNASSCRIPT): Define.
15105 * nsfns.m (as_script, as_result, as_status): New static variables.
15106 (ns_run_ascript): New function.
15107 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15108 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15109 the event loop. Get status from as_status (Bug#7276).
15111 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15112 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15113 the event loop (Bug#7276).
15115 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15117 * gnutls.c (QCgnutls_bootprop_priority)
15118 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15119 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15120 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15121 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15122 (QCgnutls_bootprop_verify_hostname_error)
15123 (QCgnutls_bootprop_callbacks_verify): Rename from
15124 Qgnutls_bootprop_..., all uses changed.
15126 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15129 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15131 * xfaces.c (Qframe_set_background_mode): Now static.
15132 * dispextern.h (Qframe_set_background_mode): Remove decl.
15134 * process.c (Fnetwork_interface_info): Declare local only if needed.
15136 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15138 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15139 (Fnetwork_interface_list): Allocate in increments of bytes instead
15140 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15141 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15143 (struct ifflag_def): notrailers is smart on OSX.
15144 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15145 Get hardware address with getifaddrs if available.
15147 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15149 * xdisp.c (iterate_out_of_display_property): xassert that
15150 IT->position is set to within IT->object's boundaries. Break from
15151 the loop as soon as EOB is reached; avoids infloops in redisplay
15152 when IT->position is set up wrongly due to some bug.
15153 Set IT->current to match the bidi iterator unconditionally.
15154 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15155 entry. Force push_it to save on the stack the current
15156 buffer/string position, to be restored by pop_it. Fix flags in
15157 the iterator structure wrt the object coming from a display
15158 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15159 properties. (Bug#9284)
15161 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15163 * fontset.c (fontset_get_font_group): Add proper type checks.
15166 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

15176 no-display-properties-and-no-overlays under bidi display.
15177 Set disp_pos in the bidi iterator to avoid searches for display
15178 properties and overlays.
15180 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15182 * editfns.c (Fset_time_zone_rule): Document relationship with the

15186 the font entity extracted from the cache (Bug#8109).
15188 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15190 * composite.c (autocmp_chars): Don't reset point. That is done by
15191 restore_point_unwind (Bug#5984).
15193 2011-08-07 Juri Linkov <juri@jurta.org>
15195 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15196 to show the arg `TIME' instead of `TIMEVAL'.
15198 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15200 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15201 display property strides EOL and includes a newline, as in
15202 longlines-mode. (Bug#9254)
15203 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15204 word-wrap under bidirectional display. (Bug#9224)
15206 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15207 is non-zero, even if the data buffer is NULL. Fixes a crash in
15208 vertical-motion with longlines-mode. (Bug#9254)
15210 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15212 * bidi.c <bidi_cache_total_alloc>: Now static.
15213 (bidi_initialize): Initialize bidi_cache_total_alloc.
15215 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15218 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15219 amount allocated this far in `bidi_cache_total_alloc'.
15220 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15221 non-zero, only free the data buffer without restoring the cache
15222 contents. All callers changed.
15224 * dispextern.h (bidi_unshelve_cache): Update prototype.
15226 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15227 (move_it_in_display_line, move_it_to)
15228 (move_it_vertically_backward, move_it_by_lines): Replace the call
15229 to xfree to an equivalent call to bidi_unshelve_cache.
15230 (move_it_in_display_line_to): Fix logic of returning
15231 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15233 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15235 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15236 came from a string character with a `cursor' property. (Bug#9229)
15238 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15240 * Makefile.in (LIB_PTHREAD): New variable.
15241 (LIBES): Add LIB_PTHREAD (Bug#9216).
15243 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15244 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15246 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15248 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15250 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15252 * xterm.c (x_find_topmost_parent): New function.
15253 (x_set_frame_alpha): Find topmost parent window with
15254 x_find_topmost_parent and set the property there also (bug#9181).
15255 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15257 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15259 * callproc.c (Fcall_process): Avoid vfork clobbering
15260 the local vars buffer, coding_systems, current_dir.
15262 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15264 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15266 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15268 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15269 so that it is not optimized away.
15271 * xdisp.c (compute_display_string_pos): Remove unused local.
15273 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15275 Fix slow cursor motion and scrolling in large buffers with
15276 selective display, like Org Mode buffers. (Bug#9218)
15278 * dispextern.h (struct bidi_it): New member disp_prop_p.
15280 * xdisp.c: Remove one-slot cache of display string positions.
15281 (compute_display_string_pos): Accept an additional argument
15282 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15283 for a display string or property. If found, set DISP_PROP_P
15286 * bidi.c (bidi_fetch_char): Accept an additional argument
15287 DISP_PROP_P, and pass it to compute_display_string_pos.
15288 Only handle text covered by a display string if DISP_PROP_P is returned
15289 non-zero. All callers of bidi_fetch_char changed.
15291 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15293 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15295 2010-12-03 Don March <don@ohspite.net>
15297 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15298 last character M-[char] is translated to ESC [char] (bug#7541).
15300 2011-08-02 Kenichi Handa <handa@m17n.org>
15302 * lisp.h (uniprop_table): Extern it.
15304 * chartab.c (uniprop_table): Make it non-static.
15306 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15308 * xdisp.c (forward_to_next_line_start): Accept additional argument
15309 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15311 (reseat_at_next_visible_line_start): Use the bidi iterator state
15312 returned by forward_to_next_line_start to restore the state of
15313 it->bidi_it after backing up to previous newline. (Bug#9212)
15315 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15317 * regex.c (re_comp): Protoize.
15318 (re_exec): Fix return type.
15319 (regexec): Fix type of `ret'. (Bug#9203)
15321 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15323 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15324 This is needed if max-image-size is a floating-point number.
15326 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15328 * print.c (print_object): Print empty symbol as ##.
15330 * lread.c (read1): Read ## as empty symbol.
15332 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15334 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15335 setting frame foreground color (Bug#9175).
15336 (x_set_background_color): Likewise.
15338 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15339 contents (Bug#9176).
15340 (EmacsTooltip -init): Remove bezels and add shadows to
15343 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15344 or scroll bar (Bug#8470).
15346 * nsfont.m (nsfont_open): Remove assignment to voffset and
15347 unnecessary vars hshink, expand, hd, full_height, min_height.
15348 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15350 * nsterm.h (nsfont_info): Remove voffset field.
15352 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15354 Implement strike-through and overline on NextStep (Bug#8863).
15356 * nsfont.m (nsfont_open): Use underline position provided by font,
15357 instead of hard-coded value of 2.
15358 (nsfont_draw): Call ns_draw_text_decoration instead.
15360 * nsterm.h: Add declaration for ns_draw_text_decoration.
15362 * nsterm.m (ns_draw_text_decoration): New function for drawing
15363 underline, overline, and strike-through.
15364 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15365 ns_draw_text_decoration. Change treatment of cursor drawing to
15366 accommodate underlining, etc.
15368 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15370 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15373 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15375 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15376 Without this fix, if a signal arrives just after memory fills up,
15377 'malloc' might be invoked reentrantly.
15379 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15380 In other words, assume that every image size is allowed, on non-X
15381 hosts. This assumption is probably wrong, but it lets Emacs compile.
15383 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15385 * regex.c (re_iswctype): Convert return values to boolean.
15387 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15389 * xdisp.c (compute_display_string_pos): Don't use cached display
15390 string position if the buffer had its restriction changed.
15393 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15395 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15397 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15399 Integer signedness and overflow and related fixes. (Bug#9079)
15401 * bidi.c: Integer size and overflow fixes.
15402 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15403 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15404 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15405 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15406 (bidi_find_other_level_edge):
15407 Use ptrdiff_t instead of EMACS_INT where either will do.
15408 This works better on 32-bit hosts configured --with-wide-int.
15409 (bidi_cache_ensure_space): Check for size-calculation overflow.
15410 Use % rather than repeated addition, for better worst-case speed.
15411 Don't set bidi_cache_size until after xrealloc returns, because it
15413 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15414 (bidi_cache_ensure_space): Also check that the bidi cache size
15415 does not exceed that of the largest Lisp string or buffer. See Eli
15416 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15418 * alloc.c (__malloc_size_t): Remove.
15419 All uses replaced by size_t. See Andreas Schwab's note
15420 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15422 * image.c: Improve checking for integer overflow.
15423 (check_image_size): Assume that f is nonnull, since
15424 it is always nonnull in practice. This is one less thing to
15425 worry about when checking for integer overflow later.
15426 (x_check_image_size): New function, which checks for integer
15427 overflow issues inside X.
15428 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15429 This removes the need for a memory_full check.
15430 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15431 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15432 (xbm_read_bitmap_data): Change locals back to 'int', since
15433 their values must fit in 'int'.
15434 (xpm_load_image, png_load, tiff_load):
15435 Invoke x_create_x_image_and_pixmap earlier,
15436 to avoid much needless work if the image is too large.
15437 (tiff_load): Treat overly large images as if
15438 x_create_x_image_and_pixmap failed, not as malloc failures.
15439 (gs_load): Use x_check_image_size.
15441 * gtkutil.c: Omit integer casts.
15442 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15443 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15445 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15447 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15448 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15449 would wrongly return t on a 64-bit host.
15451 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15452 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15453 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15454 and therefore cause GCC to emit a bogus diagnostic in some cases.
15456 * image.c: Integer signedness and overflow and related fixes.
15457 This is not an exhaustive set of fixes, but it's time to
15458 record what I've got.
15459 (lookup_pixel_color, check_image_size): Remove redundant decls.
15460 (check_image_size): Don't assume that arbitrary EMACS_INT values
15461 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15462 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15463 (tiff_load, imagemagick_load_image):
15464 Check for overflow in size calculations.
15465 (x_create_x_image_and_pixmap): Remove unnecessary test for
15466 xmalloc returning NULL; that can't happen.
15467 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15468 (xpm_color_bucket): Use better integer hashing function.
15469 (xpm_cache_color): Don't possibly over-allocate memory.
15470 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15471 (gif_memory_source):
15472 Use ptrdiff_t, not int or size_t, to record sizes.
15473 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15474 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15475 either works, as we prefer signed integers.
15476 (tiff_read_from_memory, tiff_write_from_memory):
15477 Return tsize_t, not size_t, since that's what the TIFF API wants.
15478 (tiff_read_from_memory): Don't fail simply because the read would
15479 go past EOF; instead, return a short read.
15480 (tiff_load): Omit no-longer-needed casts.
15481 (Fimagemagick_types): Don't assume size fits into 'int'.
15483 Improve hashing quality when configured --with-wide-int.
15484 * fns.c (hash_string): New function, taken from sxhash_string.
15485 Do not discard information about ASCII character case; this
15486 discarding is no longer needed.
15487 (sxhash-string): Use it. Change sig to match it. Caller changed.
15488 * lisp.h: Declare it.
15489 * lread.c (hash_string): Remove, since we now use fns.c's version.
15490 The fns.c version returns a wider integer if --with-wide-int is
15491 specified, so this should help the quality of the hashing a bit.
15493 * emacs.c: Integer overflow minor fix.
15494 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15495 Define only if GNU_LINUX.
15496 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15498 * dispnew.c: Integer signedness and overflow fixes.
15499 Remove unnecessary forward decls, that were a maintenance hassle.
15500 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15502 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15503 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15504 (prepare_desired_row, line_draw_cost):
15505 Use int, not unsigned, where either works.
15506 (save_current_matrix, restore_current_matrix):
15507 Use ptrdiff_t, not size_t, where either works.
15508 (init_display): Check for overflow more accurately, and without
15509 relying on undefined behavior.
15511 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15512 Remove, replacing with the new symbols in lisp.h. All uses changed.
15513 * fileio.c (make_temp_name):
15514 * filelock.c (lock_file_1, lock_file):
15515 * xdisp.c (message_dolog):
15516 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15517 Use pMd etc. instead.
15518 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15519 replacing the pWIDE etc. symbols removed from editfns.c.
15521 * keyboard.h (num_input_events): Now uintmax_t.
15522 This is (very slightly) less likely to mess up due to wraparound.
15525 * buffer.c: Integer signedness fixes.
15526 (alloc_buffer_text, enlarge_buffer_text):
15527 Use ptrdiff_t rather than size_t when either will do, as we prefer
15530 * alloc.c: Integer signedness and overflow fixes.
15531 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15532 (__malloc_size_t): Default to size_t, not to int.
15533 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15534 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15535 Prefer ptrdiff_t to size_t when either would do, as we prefer
15537 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15538 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15539 Now const. Initialize with values that are in range even if char
15541 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15542 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15543 These functions do the right thing with sizes > 2**32.
15544 (check_depth): Now ptrdiff_t, not int.
15545 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15546 Adjust to new way of storing sizes. Check for size overflow bugs
15548 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15549 slightly wrong anyway, as it missed one instance of
15550 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15551 (refill_memory_reserve): Omit needless cast to size_t.
15552 (mark_object_loop_halt): Mark as externally visible.
15554 * xselect.c: Integer signedness and overflow fixes.
15555 (Fx_register_dnd_atom, x_handle_dnd_message):
15556 Use ptrdiff_t, not size_t, since we prefer signed.
15557 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15558 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15559 x_dnd_atoms_size and x_dnd_atoms_length.
15561 * doprnt.c: Prefer signed to unsigned when either works.
15563 * doprnt.c (doprnt):
15565 * xdisp.c (vmessage):
15566 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15567 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15568 prefer signed arithmetic to avoid comparison confusion.
15569 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15570 but is a bit tricky.
15572 Assume freestanding C89 headers, string.h, stdlib.h.
15573 * data.c, doprnt.c, floatfns.c, print.c:
15574 Include float.h unconditionally.
15575 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15576 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15577 * regex.c: Likewise for stddef.h, string.h.
15578 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15579 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15580 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15581 (STDC_HEADERS): Remove obsolete defines.
15582 * sysdep.c: Include limits.h unconditionally.
15584 Assume support for memcmp, memcpy, memmove, memset.
15585 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15586 * regex.c (memcmp, memcpy):
15587 Remove; we assume C89 now.
15589 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15590 (__malloc_safe_bcopy): Remove; no longer needed.
15592 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15593 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15594 well either way, and we prefer signed to unsigned.
15596 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15598 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15599 closes the connection while we're reading (bug#9182).
15601 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15603 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15604 are specified (Bug#9168).
15606 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15608 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15609 Found by GCC static checking and --with-wide-int on a 32-bit host.
15611 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15613 * xdisp.c (compute_display_string_pos): Fix logic of caching
15614 previous display string position. Initialize cached_prev_pos to
15615 -1. Fixes slow-down at the beginning of a buffer.
15617 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15619 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15620 for attrs[LFACE_FONTSET_INDEX].
15622 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15624 * xml.c (parse_region): Remove unused local
15625 that was recently introduced.
15627 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15629 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15630 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15632 * xdisp.c (move_it_in_display_line_to): Record the best matching
15633 position for TO_CHARPOS while scanning the line, and restore it on
15634 exit if none of the characters scanned was an exact match.
15635 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15636 when exact match is impossible due to invisible text, and the
15637 lines are truncated.
15639 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15641 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15644 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15646 Fix a significant slow-down of cursor motion with C-n, C-p,
15647 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15648 auto-repeat under bidi redisplay in fontified buffers.
15649 * xdisp.c (compute_stop_pos_backwards): New function.
15650 (next_element_from_buffer): Call compute_stop_pos_backwards to
15651 find a suitable prev_stop when we find ourselves before
15653 (reseat): Don't look for prev_stop, as that could mean a very long
15655 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15656 <cached_disp_overlay_modiff>: Cache for last found display string
15658 (compute_display_string_pos): Return the cached position if asked
15659 about the same buffer in the same area of character positions, and
15660 the buffer wasn't changed since the time the display string
15661 position was cached.
15663 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15665 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15666 is an integer, which is important for empty lines. (Bug#9149)
15668 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15670 * frame.c (Fmodify_frame_parameters): In tty case, update the
15671 default face if necessary (Bug#4238).
15673 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15675 * editfns.c (Fstring_to_char): No need to explain what a character
15676 is in the docstring (Bug#6576).
15678 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15680 * xml.c (parse_region): Make sure we always return a tree.
15682 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15684 * xml.c (parse_region): If a document contains only comments,
15687 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15689 * xml.c (make_dom): Return comments, too.
15691 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15694 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15695 and the surrounding thread.
15696 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15697 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15698 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15700 * s/openbsd.h (BROKEN_SIGIO): Define.
15701 * unexelf.c (unexec) [__OpenBSD__]:
15702 Don't update the .mdebug section of the Alpha COFF symbol table.
15704 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15706 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15709 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15711 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15712 This fixes some race conditions on the permissions of any newly
15715 * alloc.c (valid_pointer_p): Use pipe, not open.
15716 This fixes some permissions issues when debugging.
15718 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15719 If fchown fails to set both uid and gid, try to set just gid,
15720 as that is sometimes allowed. Adjust the file's mode to eliminate
15721 setuid or setgid bits that are inappropriate if fchown fails.
15723 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15725 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

15731 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15733 * lread.c (read_integer): Unread even EOF character.
15734 (read1): Likewise. Properly record start position of symbol.

15737 symbol character follows.
15739 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15741 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15742 This works around a problem with the previous change to Fcopy_file.
15743 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15744 and without this change, GCC might complain about discarding
15745 fchown's return value.
15747 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15749 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15751 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15753 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15755 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15757 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15758 it's used from the C level.
15760 * process.c: Use the same condition for POLL_FOR_INPUT in both
15761 keyboard.c and process.c (bug#1858).
15763 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15765 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15766 (Fgnutls_boot): Use it.
15768 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15770 * doc.c (Fsubstitute_command_keys): Revert last change.
15772 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15774 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15775 quotes the next character, and doesn't affect other longer
15776 sequences (bug#8935).
15778 * lread.c (syms_of_lread): Clarify that is isn't only
15779 `eval-buffer' and `eval-defun' that's affected by
15780 `lexical-binding' (bug#8460).
15782 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15784 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15785 bidi redisplay when a line includes both an image and is truncated.
15787 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15789 Fix minor problems found by static checking.
15790 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15791 (elsz): Now a signed constant, not a size_t var. We prefer signed
15792 types to unsigned, to avoid integer comparison confusion. Without
15793 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15794 "cannot optimize loop, the loop counter may overflow", a symptom
15796 * indent.c (Fvertical_motion): Mark locals as initialized.
15797 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15799 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

15822 buffer position was specified. Initialize paragraph_embedding to
15824 (reseat_to_string): Initialize the bidi iterator.
15825 (display_string): If we need to ignore text properties of
15826 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15827 original value of -1 will not work with bidi.)
15828 (compute_display_string_pos): First arg is now struct
15829 `text_pos *'; all callers changed. Support display properties on
15831 (compute_display_string_end): Support display properties on Lisp
15833 (init_iterator, reseat_1, reseat_to_string): Initialize the
15834 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15835 when iterating on a string not from display properties).
15836 (compute_display_string_pos, compute_display_string_end):
15837 Fix calculation of the object to scan. Fixes an error when using
15839 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15840 base_level_stop; instead, set base_level_stop to BEGV.
15841 Fixes crashes in vertical-motion.
15842 (next_element_from_buffer): Improve commentary for when
15843 the iterator is before prev_stop.
15844 (init_iterator): Initialize bidi_p from the default value of
15845 bidi-display-reordering, not from buffer-local value. Use the
15846 buffer-local value only if initializing for buffer iteration.

15855 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15856 (init_iterator): Don't initialize it->bidi_p for strings
15858 (reseat_to_string): Initialize it->bidi_p for strings here.

15866 (get_visually_first_element): New function, refactored from common
15867 parts of next_element_from_buffer, next_element_from_string, and
15868 next_element_from_c_string.

15870 (display_menu_bar): Force left-to-right direction. Add a FIXME
15871 comment for making that be controlled by a user option.

15880 (get_overlay_strings_1, push_display_prop): Set up the bidi
15881 iterator for displaying display or overlay strings.
15882 (forward_to_next_line_start): Don't use the shortcut if
15884 (back_to_previous_visible_line_start): If handle_display_prop
15885 pushed the iterator stack, restore the internal state of the bidi
15886 iterator by calling bidi_pop_it same number of times.
15887 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15888 and we are bidi-iterating, don't decrement the iterator position;
15889 instead, set the first_elt flag in the bidi iterator, to produce
15891 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15892 (push_display_prop): xassert that we are iterating a buffer.
15893 (push_it, pop_it): Save and restore paragraph_embedding member.
15894 (handle_single_display_spec, next_overlay_string)
15895 (get_overlay_strings_1, reseat_1, reseat_to_string)
15896 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15897 correctly. Don't assume unibyte strings are not bidi-reordered.

15906 property. Fix a typo in popping stretch info. Add an assertion
15907 for verifying that the iterator position is in sync with the bidi
15909 (handle_single_display_spec, get_overlay_strings_1)

15934 displayed in margins. (Bug#8133) (Bug#8867)
15935 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
15937 (pos_visible_p): Support positions in bidi-reordered lines.
15938 Save and restore bidi cache.
15940 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

15963 changed to -1 and -2, respectively.
15964 (bidi_char_at_pos): New function.
15965 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16051 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16053 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16054 The old code sometimes used this field without initializing it.
16056 * alloc.c (gc_sweep): Don't read past end of array.
16057 In theory, the old code could also have corrupted Emacs internals,
16058 though it'd be very unlikely.

16162 sigprocmask is portable only for single-threaded applications, and

16324 if Emacs is configured with --with-wide-int.
16325 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

16362 Random fixes. E.g., (random) never returned negative values.
16363 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16364 subseconds part to the entropy, as that's a bit more random.
16365 Prefer signed to unsigned, since the signedness doesn't matter and
16366 in general we prefer signed. When given a limit, use a
16367 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16368 latter isn't right if USE_2_TAGS_FOR_INTS.
16369 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16370 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16382 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16383 This is more efficient than Ffile_directory_p and avoids a minor race.

16387 * buffer.c (Foverlay_put): Say what the return value is
16390 * fileio.c (barf_or_query_if_file_exists): Check first if the file

16394 error be more correct.
16396 * fns.c (Frequire): Remove the mention of the .gz files, since

16413 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16414 Also (re)move comments that are misplaced or no longer relevant.

16443 * lread.c (syms_of_lread): Mention single symbols defined by

16500 with value as argument.
16501 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
16502 g_settings_new (Bug#8967). Do not create gsettings_obj.

16510 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
16513 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
16515 * eval.c (struct backtrace): Simplify and port the data structure.
16516 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16517 signed bit field, as this assumption is not portable and it makes
16518 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16519 "char debug_on_exit : 1" as this is not portable either; instead,
16520 use the portable "unsigned int debug_on_exit : 1". Remove unused
16521 member evalargs. Remove obsolete comments about cc bombing out.
16523 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16591 (emacs_fixed_new): Set priv->f to argument.
16592 (emacs_fixed_get_preferred_width)
16593 (emacs_fixed_get_preferred_height): Use min_width/height from
16594 frames size_hint to set minimum and natural (Bug#8919).
16595 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16596 and use min_width/height from frames size_hint to set
16597 min_width/height (Bug#8919).

16617 Use gnulib's dup2 module instead of rolling our own.
16618 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

16685 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16687 Integer and buffer overflow fixes (Bug#8873).
16689 * print.c (printchar, strout): Check for string overflow.
16690 (PRINTPREPARE, printchar, strout):
16691 Don't set size unless allocation succeeds.
16693 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16694 for sizes. Check for string overflow more accurately.
16695 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16697 * macros.c: Integer and buffer overflow fixes.
16698 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16699 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

16702 Check for size-calculation overflow.
16703 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16705 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16707 * lread.c: Integer overflow fixes.
16708 (read_integer): Radix is now EMACS_INT, not int,
16709 to improve quality of diagnostics for out-of-range radices.
16710 Calculate buffer size correctly for out-of-range radices.
16711 (read1): Check for integer overflow in radices, and in
16712 read-circle numbers.
16713 (read_escape): Avoid int overflow.
16714 (Fload, openp, read_buffer_size, read1)
16715 (substitute_object_recurse, read_vector, read_list, map_obarray):
16716 Use ptrdiff_t, not int, for sizes.

16731 2011-06-22 Leo Liu <sdl.web@gmail.com>
16733 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16734 Move to minibuffer.el.
16736 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16738 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16739 The following patches are for when GLYPH_DEBUG && !XASSERT.
16740 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16741 * dispnew.c (flush_stdout):
16742 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16743 Mark as externally visible.
16744 * dispnew.c (check_window_matrix_pointers): Now static.
16745 * dispnew.c (window_to_frame_vpos):
16746 * xfns.c (unwind_create_frame):
16747 * xterm.c (x_check_font): Remove unused local.
16748 * scroll.c (CHECK_BOUNDS):
16749 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16750 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16751 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16752 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16753 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16755 (debug_method_add): Use va_list and vsprintf rather than relying
16756 on undefined behavior with wrong number of arguments.
16757 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16758 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16759 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16760 since we're not interested in debugging glyphs with old libraries.
16761 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16762 GCC 4.6.0's static checking.
16764 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16766 Integer overflow and signedness fixes (Bug#8873).
16767 A few related buffer overrun fixes, too.

16776 (x_create_bitmap_from_xpm_data):
16777 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16778 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16780 * xfaces.c (load_pixmap):
16781 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16782 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16783 (.bitmaps_last, struct x_output.icon_bitmap):
16784 Use ptrdiff_t, not int, for bitmap indexes.
16785 (x_allocate_bitmap_record): Check for size overflow.
16786 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16788 Use ptrdiff_t, not int, for overlay counts.
16789 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16790 * editfns.c (overlays_around, get_pos_property):
16791 * textprop.c (get_char_property_and_overlay):
16792 * xdisp.c (next_overlay_change, note_mouse_highlight):
16793 * xfaces.c (face_at_buffer_position):
16794 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16795 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16796 (Fnext_overlay_change, Fprevious_overlay_change)
16797 (mouse_face_overlay_overlaps, Foverlays_in):
16798 Use ptrdiff_t, not int, for sizes.
16799 (overlays_at, overlays_in): Check for size-calculation overflow.
16801 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16803 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16804 (x_session_initialize): Do not assume string length fits in int.
16806 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16807 This is unlikely, but can occur if DPI is outlandish.
16809 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16810 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16812 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16813 * xrdb.c (magic_file_p, search_magic_path):
16814 Omit last arg SUFFIX; it was always 0. All callers changed.
16815 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16817 * xfont.c (xfont_match): Avoid need for strlen.
16819 * xfns.c: Don't assume strlen fits in int.

16822 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16823 not unsigned long, as we prefer signed integers. All callers changed.
16824 Detect integer overflow in repeat count.
16825 (message_dolog): Don't assume print length fits in 39 bytes.
16826 (display_mode_element): Don't assume strlen fits in int.
16828 * termcap.c: Don't assume sizes fit in int and never overflow.
16829 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16830 (gobble_line): Check for size-calculation overflow.
16832 * minibuf.c (Fread_buffer):
16833 * lread.c (intern, intern_c_string):
16834 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16835 Don't assume string length fits in int.

16844 Don't assume integer property fits in fixnum.
16845 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16847 * filelock.c: Fix some buffer overrun and integer overflow issues.
16848 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16849 Reformulate so as not to need the command string.
16850 Invoke gzip -cd rather than gunzip, as it's more portable.
16851 (lock_info_type, lock_file_1, lock_file):
16852 Don't assume pid_t and time_t fit in unsigned long.
16853 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16854 (current_lock_owner): Prefer signed type for sizes.
16855 Use memcpy, not strncpy, where memcpy is what is really wanted.
16856 Don't assume (via atoi) that time_t and pid_t fit in int.
16857 Check for time_t and/or pid_t out of range, e.g., via a network share.
16858 Don't alloca where an auto var works fine.
16860 * fileio.c: Fix some integer overflow issues.
16861 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16862 Don't assume string length fits in int.
16863 (directory_file_name): Don't assume string length fits in long.
16864 (make_temp_name): Don't assume pid fits in int, or that its print
16865 length is less than 20.
16867 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16869 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16871 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16873 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

16876 * emacs.c: Don't assume string length fits in 'int'.
16877 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16878 (main): Don't invoke strlen when not needed.

16883 * callproc.c (getenv_internal_1, getenv_internal)
16884 (Fgetenv_internal):
16885 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16887 * lread.c (invalid_syntax): Omit length argument.
16888 All uses changed. This doesn't fix a bug, but it simplifies the
16889 code away from its former Hollerith-constant appearance, and it's
16890 one less 'int' to worry about when looking at integer-overflow issues.
16891 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16893 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16894 This didn't break anything, but it didn't help either.
16895 It's confusing to put a bogus integer in a place where the actual
16896 value does not matter.
16897 (LIST_END_P): Remove unused macro and its bogus comment.
16898 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16900 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16901 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16903 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16904 We prefer signed types, and the value cannot exceed the EMACS_INT
16905 range anyway (because otherwise the length would not be representable).
16906 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16907 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16908 This avoids a GCC warning when WIDE_EMACS_INT.
16910 * indent.c (sane_tab_width): New function.
16911 (current_column, scan_for_column, Findent_to, position_indentation)
16912 (compute_motion): Use it. This is just for clarity.
16913 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16915 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16917 * lisp.h (lint_assume): New macro.
16918 * composite.c (composition_gstring_put_cache):
16919 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16921 * editfns.c, insdel.c:
16922 Omit unnecessary forward decls, to simplify future changes.
16924 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16926 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16928 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16929 Use much-faster test for byte-length change.
16930 Don't assume string byte-length fits in 'int'.
16931 Check that character arg fits in 'int'.
16932 (mapcar1): Declare byte as byte, for clarity.
16934 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16936 * fns.c (concat): Catch string overflow earlier.
16937 Do not rely on integer wraparound.
16939 * dispextern.h (struct it.overlay_strings_charpos)
16940 (struct it.selective): Now EMACS_INT, not int.
16941 * xdisp.c (forward_to_next_line_start)
16942 (back_to_previous_visible_line_start)
16943 (reseat_at_next_visible_line_start, next_element_from_buffer):
16944 Don't arbitrarily truncate the value of 'selective' to int.
16946 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16948 * composite.c: Don't truncate sizes to 'int'.
16949 (composition_gstring_p, composition_reseat_it)
16950 (composition_adjust_point): Use EMACS_INT, not int.
16951 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16952 not EMACS_UINT, for indexes.
16954 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16956 * buffer.c: Include <verify.h>.
16957 (struct sortvec.priority, struct sortstr.priority):
16958 Now EMACS_INT, not int.
16959 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16960 (struct sortstr.size, record_overlay_string)
16961 (struct sortstrlist.size, struct sortlist.used):
16962 Don't truncate size to int.
16963 (record_overlay_string): Check for size-calculation overflow.
16964 (init_buffer_once): Check at compile-time, not run-time.
16966 2011-06-22 Jim Meyering <meyering@redhat.com>
16968 Don't leak an XBM-image-sized buffer
16969 * image.c (xbm_load): Free the image buffer after using it.
16971 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16974 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16975 that Sun C diagnosed.
16976 * fns.c (secure_hash): Fix pointer signedness issue.
16977 * intervals.c (static_offset_intervals): New function.
16978 (offset_intervals): Use it.
16980 2011-06-21 Leo Liu <sdl.web@gmail.com>
16983 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16986 * fns.c (secure_hash): Rename from crypto_hash_function and change
16987 the first arg to accept symbols.
16988 (Fsecure_hash): New primitive.
16989 (syms_of_fns): New symbols.
16991 2011-06-20 Deniz Dogan <deniz@dogan.se>
16993 * process.c (Fset_process_buffer): Clarify return value in
16996 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16998 * dispnew.c (add_window_display_history): Use BVAR.
17000 * xdisp.c (debug_method_add): Use BVAR.
17001 (check_window_end, dump_glyph_matrix, dump_glyph)
17002 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17004 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17007 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17008 check till after the cache is created in init_frame_faces.
17010 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17012 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17014 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17016 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17017 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17018 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17020 Improve buffer-overflow checking (Bug#8873).
17021 * fileio.c (Finsert_file_contents):
17022 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17023 Remove the old (too-loose) buffer overflow checks.
17024 They weren't needed, since make_gap checks for buffer overflow.
17025 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17026 The old code merely checked for Emacs fixnum overflow, and relied
17027 on undefined (wraparound) behavior. The new code avoids undefined
17028 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17030 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17031 Tune. Don't use wider integers than needed. Don't use alloca.
17032 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17034 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17036 * insdel.c, lisp.h (buffer_overflow): New function.
17037 (insert_from_buffer_1, replace_range, replace_range_2):
17038 * insdel.c (make_gap_larger):
17039 * editfns.c (Finsert_char):
17040 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17042 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17044 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17046 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17048 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17049 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17051 * fileio.c: Don't assume EMACS_INT fits in off_t.
17052 (emacs_lseek): New static function.
17053 (Finsert_file_contents, Fwrite_region): Use it.
17054 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17056 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17058 * fns.c: Don't overflow int when computing a list length.
17059 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17060 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17061 truncation on 64-bit hosts. Check for QUIT every
17062 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17063 faster and is responsive enough.
17064 (Flength): Report an error instead of overflowing an integer.
17065 (Fsafe_length): Return a float if the value is not representable
17066 as a fixnum. This shouldn't happen except in contrived situations.
17067 (Fnthcdr, Fsort): Don't assume list length fits in int.
17068 (Fcopy_sequence): Don't assume vector length fits in int.
17070 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17071 (header_size, word_size): New constants.
17072 (allocate_vectorlike): Don't check size overflow here.
17073 (allocate_vector): Check it here instead, since this is the only
17074 caller of allocate_vectorlike that could cause overflow.
17075 Check that the new vector's length is representable as a fixnum.
17077 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17078 The previous code was bogus. For example, next_almost_prime (32)
17079 returned 39, which is undesirable as it is a multiple of 3; and
17080 next_almost_prime (24) returned 25, which is a multiple of 5 so
17081 why was the code bothering to check for multiples of 7?
17083 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17085 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17087 Variadic C functions now count arguments with ptrdiff_t.
17088 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17089 Back then I didn't know that the Emacs coding style prefers signed int.
17090 Also, in the meantime I found a few more instances where arguments
17091 were being counted with int, which may truncate counts on 64-bit
17092 machines, or EMACS_INT, which may be unnecessarily wide.
17093 * lisp.h (struct Lisp_Subr.function.aMANY)
17094 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17095 Arg counts are now ptrdiff_t, not size_t.
17096 All variadic functions and their callers changed accordingly.
17097 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17098 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17099 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17100 * callint.c (Fcall_interactively): Check arg count for overflow,
17101 to avoid potential buffer overrun. Use signed char, not 'int',
17102 for 'varies' array, so that we needn't bother to check its size
17103 calculation for overflow.
17104 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17105 * eval.c (apply_lambda):
17106 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17107 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17108 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17110 * callint.c (Fcall_interactively): Don't use index var as event count.
17112 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17113 * mem-limits.h (SIZE): Remove; no longer used.
17115 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17117 Remove unnecessary casts.
17118 * xterm.c (x_term_init):
17119 * xfns.c (x_set_border_pixel):
17120 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17121 These aren't needed now that we assume ANSI C.
17123 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17124 It's more likely to cause problems (due to unsigned overflow)
17127 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17129 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17131 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17133 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17135 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17137 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17139 GLYPH_CODE_FACE returns EMACS_INT, not int.
17140 * dispextern.h (merge_faces):
17141 * xfaces.c (merge_faces):
17142 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17143 Don't assume EMACS_INT fits in int.
17145 * character.h (CHAR_VALID_P): Remove unused parameter.
17146 * fontset.c, lisp.h, xdisp.c: All uses changed.
17148 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17150 * fns.c (concat): Minor tuning based on overflow analysis.
17151 This doesn't fix any bugs. Use int to hold character, instead
17152 of constantly refetching from Emacs object. Use XFASTINT, not
17153 XINT, for value known to be a character. Don't bother comparing
17154 a single byte to 0400, as it's always less.
17156 * floatfns.c (Fexpt):
17157 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17159 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17162 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17164 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17165 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17166 incorrectly succeed when S was a string, because 4294967386 was
17167 truncated before it was used.
17169 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17170 Otherwise, an out-of-range integer could cause undefined behavior
17173 * composite.c: Use int, not EMACS_INT, for characters.
17174 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17175 EMACS_INT, for values that are known to be in character range.
17176 This doesn't fix any bugs but is the usual style inside Emacs and
17177 may generate better code on 32-bit machines.
17179 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17180 This is for reasons similar to the recent CHAR_STRING fix.
17181 * charset.c (Fencode_char): Check that character arg is actually
17182 a character. Pass an int to ENCODE_CHAR.
17183 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17184 wider than 'int', as a compile-time check to prevent future regressions
17187 * character.c (char_string): Remove unnecessary casts.
17189 Make sure a 64-bit char is never passed to CHAR_STRING.
17190 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17191 by silently ignoring the top 32 bits, allowing some values
17192 that were far too large to be valid characters.
17193 * character.h: Include <verify.h>.
17194 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17195 arguments are no wider than unsigned, as a compile-time check
17196 to prevent future regressions in this area.
17198 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17199 (Fsubst_char_in_region):
17201 * xdisp.c (decode_mode_spec_coding):
17202 Adjust to CHAR_STRING's new requirement.
17203 * editfns.c (Finsert_char, Fsubst_char_in_region):
17204 * fns.c (concat): Check that character args are actually
17205 characters. Without this test, these functions did the wrong
17206 thing with wildly out-of-range values on 64-bit hosts.
17208 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17209 These casts should not be needed on 32-bit hosts, either.
17210 * keyboard.c (read_char):
17211 * lread.c (Fload): Remove casts to unsigned.
17213 * lisp.h (UNSIGNED_CMP): New macro.
17214 This fixes comparison bugs on 64-bit hosts.
17215 (ASCII_CHAR_P): Use it.
17216 * casefiddle.c (casify_object):
17217 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17218 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17219 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17220 * dispextern.h (FACE_FROM_ID):
17221 * keyboard.c (read_char): Use UNSIGNED_CMP.
17223 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17224 not to EMACS_INT, to avoid GCC warning.
17226 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17228 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17229 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17230 isn't needed on 32-bit machines.
17232 * buffer.c (Fgenerate_new_buffer_name):
17233 Use EMACS_INT for count, not int.
17234 (advance_to_char_boundary): Return EMACS_INT, not int.
17236 * data.c (Qcompiled_function): Now static.
17238 * window.c (window_body_lines): Now static.
17240 * image.c (gif_load): Rename local to avoid shadowing.
17242 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17243 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17244 * alloc.c (make_save_value): Integer argument is now of type
17245 ptrdiff_t, not int.
17246 (mark_object): Use ptrdiff_t, not int.
17247 * lisp.h (pD): New macro.
17248 * print.c (print_object): Use it.
17250 * alloc.c: Use EMACS_INT, not int, to count objects.
17251 (total_conses, total_markers, total_symbols, total_vector_size)
17252 (total_free_conses, total_free_markers, total_free_symbols)
17253 (total_free_floats, total_floats, total_free_intervals)
17254 (total_intervals, total_strings, total_free_strings):
17255 Now EMACS_INT, not int. All uses changed.
17256 (Fgarbage_collect): Compute overall total using a double, so that
17257 integer overflow is less likely to be a problem. Check for overflow
17258 when converting back to an integer.
17259 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17260 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17261 These were 'int' variables that could overflow on 64-bit hosts;
17262 they were never used, so remove them instead of repairing them.
17263 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17264 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17265 Previously, this ceilinged at INT_MAX, but that doesn't work on
17267 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17269 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17270 (allocate_vectorlike): Check for ptrdiff_t overflow.
17271 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17272 when a (possibly-narrower) signed value would do just as well.
17273 We prefer using signed arithmetic, to avoid comparison confusion.
17275 * alloc.c: Catch some string size overflows that we were missing.
17276 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17277 for convenience in STRING_BYTES_MAX.
17278 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17279 The definition here is exact; the one in lisp.h was approximate.
17280 (allocate_string_data): Check for string overflow. This catches
17281 some instances we weren't catching before. Also, it catches
17282 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17283 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17284 and ptrdiff_t and EMACS_INT are both 64 bits.
17286 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17287 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17288 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17290 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17292 * alloc.c (Fmake_string): Check for out-of-range init.
17294 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17296 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17298 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17300 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17301 xg_get_default_scrollbar_width.
17303 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17304 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17305 (style_changed_cb): Call update_theme_scrollbar_width and call
17306 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17307 all frames (Bug#8505).
17308 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17309 Call gtk_window_set_resizable if HAVE_GTK3.
17310 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17311 and height if HAVE_GTK3 (Bug#8505).
17312 (scroll_bar_width_for_theme): New variable.
17313 (update_theme_scrollbar_width): New function.
17314 (xg_get_default_scrollbar_width): Move code to
17315 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17316 (xg_initialize): Call update_theme_scrollbar_width.
17318 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17320 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17322 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17324 * frame.c (make_frame): Call other_buffer_safely instead of
17327 * window.c (temp_output_buffer_show): Call display_buffer with
17328 second argument Vtemp_buffer_show_specifiers and reset latter
17329 immediately after the call.
17330 (Vtemp_buffer_show_specifiers): New variable.
17331 (auto_window_vscroll_p, next_screen_context_lines)
17332 (Vscroll_preserve_screen_position): Remove leading asterisks from
17335 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17337 Fix minor problems found by GCC 4.6.0 static checking.
17338 * buffer.c (Qclone_number): Remove for now, as it's unused.
17339 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17340 (record_buffer): Remove unused local.
17341 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17342 (set_frame_buffer_list): Remove; unused.
17343 * frame.h (other_visible_frames): Remove decl.
17344 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
17345 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
17346 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
17348 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
17349 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
17350 Define only if HAVE_GPM.
17351 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
17352 (update_hints_inhibit): Remove; never set. All uses removed.
17353 * widgetprv.h (emacsFrameClassRec): Remove decl.
17354 * window.c (delete_deletable_window): Now returns void, since it
17355 wasn't returning anything.
17356 (compare_window_configurations): Remove unused locals.
17357 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
17358 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
17359 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
17360 the same widths as pointers. This follows up on the 2011-05-06 patch.
17361 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
17362 * xterm.h: Likewise.
17363 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
17365 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
17367 * makefile.w32-in: Update dependencies.

17825 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
17826 New error handlers.
17827 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
17828 Obey Vx_select_enable_clipboard_manager. Catch errors in
17829 x_clipboard_manager_save (Bug#8779).
17830 (Vx_select_enable_clipboard_manager): New variable.
17831 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
17833 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
17835 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
17837 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17839 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
17840 in the current matrix if keep_current_p is non-zero.
17842 2011-06-04 Eli Zaretskii <eliz@gnu.org>
17844 * bidi.c (bidi_level_of_next_char): Fix last change.
17846 2011-06-03 Eli Zaretskii <eliz@gnu.org>
17848 Support bidi reordering of text covered by display properties.
17850 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
17851 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
17852 (bidi_cache_search, bidi_cache_iterator_state)
17853 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
17854 (bidi_level_of_next_char, bidi_move_to_visually_next):
17855 Support character positions inside a run of characters covered by a
17857 (bidi_paragraph_init, bidi_resolve_explicit_1)
17858 (bidi_level_of_next_char): Call bidi_fetch_char and
17859 bidi_fetch_char_advance instead of FETCH_CHAR and
17860 FETCH_CHAR_ADVANCE.
17861 (bidi_init_it): Initialize new members.
17862 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
17864 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
17865 instead of using explicit *_CHAR codes.
17866 (bidi_resolve_explicit, bidi_resolve_weak):
17867 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
17868 bidirectional text is supported only in multibyte buffers.
17869 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
17870 it to initialize the frame_window_p member of struct bidi_it.
17871 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
17872 (bidi_resolve_explicit, bidi_resolve_weak)

17874 bidi_it->nchars is non-positive.
17875 (bidi_level_of_next_char): Don't try to lookup the cache for the
17876 next/previous character if nothing is cached there yet, or if we
17877 were just reseat()'ed to a new position.
17879 * xdisp.c (set_cursor_from_row): Set start and stop points
17880 according to the row's direction when priming the loop that looks
17881 for the glyph on which to display cursor.
17882 (single_display_spec_intangible_p): Function deleted.
17883 (display_prop_intangible_p): Reimplement to call
17884 handle_display_spec instead of single_display_spec_intangible_p.
17885 Accept 3 additional arguments needed by handle_display_spec.
17886 This fixes incorrect cursor motion across display property with complex
17887 values: lists, `(when COND...)' forms, etc.
17888 (single_display_spec_string_p): Support property values that are
17889 lists with the argument STRING its top-level element.
17890 (display_prop_string_p): Fix the condition for processing a
17891 property that is a list to be consistent with handle_display_spec.
17892 (handle_display_spec): New function, refactored from the
17893 last portion of handle_display_prop.
17894 (compute_display_string_pos): Accept additional argument
17895 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17896 value of a `display' property is a "replacing spec".
17897 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17898 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17899 the display property, but just return a value indicating whether
17900 the display property will replace the characters it covers.
17901 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17902 frame_window_p members of struct bidi_it.
17903 (compute_display_string_pos, compute_display_string_end):
17905 (push_it): Accept second argument POSITION, where pop_it should
17906 jump to continue iteration.
17907 (reseat_1): Initialize bidi_it.disp_pos.
17909 * keyboard.c (adjust_point_for_property): Adjust the call to
17910 display_prop_intangible_p to its new signature.
17912 * dispextern.h (struct bidi_it): New member frame_window_p.
17913 (bidi_init_it): Update prototypes.
17914 (display_prop_intangible_p): Update prototype.
17915 (compute_display_string_pos, compute_display_string_end):
17916 Declare prototypes.
17917 (struct bidi_it): New members nchars and disp_pos. ch_len is now
17920 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17922 Malloc failure behavior now depends on size of allocation.
17923 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17924 * lisp.h: Change signatures accordingly.
17925 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17926 All callers changed. (Bug#8762)
17928 * gnutls.c: Use Emacs's memory allocators.
17929 Without this change, the gnutls library would invoke malloc etc.
17930 directly, which causes problems on non-SYNC_INPUT hosts, and which
17931 runs afoul of improving memory_full behavior. (Bug#8761)
17932 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17933 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17934 xfree instead of the default malloc, realloc, free.
17935 (Fgnutls_boot): No need to check for memory allocation failure,
17936 since xmalloc does that for us.
17938 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17939 * category.c (hash_get_category_set):
17940 * ccl.c (ccl_driver):
17941 * charset.c (Fdefine_charset_internal):
17942 * charset.h (struct charset.hash_index):

17944 (composition_gstring_put_cache):
17945 * composite.h (struct composition.hash_index):
17946 * dispextern.h (struct image.hash):
17947 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
17948 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
17949 (hashfn_equal, hashfn_user_defined, make_hash_table)
17950 (maybe_resize_hash_table, hash_lookup, hash_put)
17951 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
17952 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17953 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17954 * image.c (make_image, search_image_cache, lookup_image)
17955 (xpm_put_color_table_h):
17956 * lisp.h (struct Lisp_Hash_Table):
17957 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17958 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17959 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17960 * alloc.c (allocate_vectorlike):
17961 Check for overflow in vector size calculations.
17962 * ccl.c (ccl_driver):
17963 Check for overflow when converting EMACS_INT to int.
17964 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17965 need to be updated by these changes.
17966 * fns.c (make_hash_table, maybe_resize_hash_table):
17967 Check for integer overflow with large hash tables.
17968 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17969 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17970 (SXHASH_REDUCE): New macro.
17971 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17972 Use it instead of discarding useful hash info with large hash values.
17973 (sxhash_float): New function.
17974 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17975 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17976 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17977 Rewrite to use FIXNUM_BITS, as this simplifies things.
17978 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17979 Adjust signatures to match updated version of code.
17980 (consing_since_gc): Now EMACS_INT, since a single hash table can
17981 use more than INT_MAX bytes.
17983 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17985 Make it possible to build with GCC-4.6+ -O2 -flto.
17987 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17989 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17991 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17992 Call minibuffer-inactive-mode.
17994 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17996 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17997 Update dependencies.
17999 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18001 * data.c (init_data): Remove code for UTS, this system is not
18004 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18006 Don't force ./temacs to start in terminal mode.
18008 * frame.c (make_initial_frame): Initialize faces in all cases, not
18009 only when CANNOT_DUMP is defined.
18010 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18012 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18014 * dispnew.c (add_window_display_history): Use const for the string
18015 pointer. Remove declaration, not needed.
18017 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18019 Use 'inline', not 'INLINE'.
18020 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18021 * alloc.c, fontset.c (INLINE): Remove.
18022 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18023 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18024 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18025 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18026 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18028 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18030 Make it possible to run ./temacs.
18032 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18033 syms_of_callproc does the same thing. Remove test for
18034 "initialized", do it in the caller.
18035 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18037 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18039 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18040 (read_minibuf): Use get_minibuffer.
18041 (syms_of_minibuf): Use DEFSYM.
18042 (Qmetadata): New var.
18043 * data.c (Qbuffer): Don't make it static.
18044 (syms_of_data): Use DEFSYM.
18046 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18048 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18049 (CCL_CODE_MIN): New macro.
18051 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18053 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18055 * eval.c (Qdebug): Now static.
18056 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18057 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18058 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18060 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18062 * image.c: Various fixes to ImageMagick code comments.
18063 (Fimagemagick_types): Doc fix.
18065 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18067 Minor fixes prompted by GCC 4.6.0 warnings.
18069 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18071 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18072 (x_clipboard_manager_save_all): Move extern decl to ...
18073 * xterm.h: ... here, so that it can be checked for consistency.
18075 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18077 * xselect.c (x_clipboard_manager_save_frame)
18078 (x_clipboard_manager_save_all): New functions.
18079 (Fx_clipboard_manager_save): Lisp function deleted.
18081 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18082 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18084 * xterm.h: Update prototype.
18086 2011-05-28 William Xu <william.xwl@gmail.com>
18088 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18089 exiting (Bug#8239).
18091 2011-05-28 Jim Meyering <meyering@redhat.com>
18093 Avoid a sign-extension bug in crypto_hash_function.
18094 * fns.c (to_uchar): Define.
18095 (crypto_hash_function): Use it to convert some newly-signed
18096 variables to unsigned, to avoid sign-extension bugs. For example,
18097 without this change, (md5 "truc") would evaluate to
18098 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18099 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18100 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18102 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18104 Integer overflow fixes.
18106 * dbusbind.c: Serial number integer overflow fixes.
18107 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18108 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18109 to hold a serial number that is too large for a fixnum.
18110 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18111 Check for serial numbers out of range. Decode any serial number
18112 that was so large that it became a float. (Bug#8722)
18114 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18115 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18116 Use XFASTINT rather than XUINT when numbers are nonnegative.
18117 (xd_append_arg, Fdbus_method_return_internal):
18118 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18119 arguments, check that Lisp number is nonnegative, rather than
18120 silently wrapping negative numbers around. (Bug#8722)
18121 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18124 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18126 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18128 ccl: Add integer overflow checks.
18129 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18130 (IN_INT_RANGE): New macros.
18131 (ccl_driver): Use them to check for integer overflow when
18132 decoding a CCL program. Many of the new checks are whether XINT (x)
18133 fits in int; it doesn't always, on 64-bit hosts. The new version
18134 doesn't catch all possible integer overflows, but it's an
18135 improvement. (Bug#8719)
18137 * alloc.c (make_event_array): Use XINT, not XUINT.
18138 There's no need for unsigned here.
18140 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18141 This follows up to the 2011-05-06 change that substituted uintptr_t
18142 for EMACS_INT. This case wasn't caught back then.
18144 Rework Fformat to avoid integer overflow issues.
18145 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18146 now (part of C89). Include <verify.h>.
18147 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18148 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18149 (Fformat): Avoid the prepass trying to compute sizes; it was only
18150 approximate and thus did not catch overflow reliably. Instead, walk
18151 through the format just once, formatting and computing sizes as we go,
18152 checking for integer overflow at every step, and allocating a larger
18153 buffer as needed. Keep track separately whether the format is
18154 multibyte. Keep only the most-recently calculated precision, rather
18155 than them all. Record whether each argument has been converted to
18156 string. Use EMACS_INT, not int, for byte and char and arg counts.
18157 Support field widths and precisions larger than INT_MAX. Avoid
18158 sprintf's undefined behavior with conversion specifications such as %#d
18159 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18160 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18161 formatting out-of-range floating point numbers with int
18162 formats. (Bug#8668)
18164 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18166 * data.c: Avoid integer truncation in expressions involving floats.
18167 * data.c: Include <intprops.h>.
18168 (arith_driver): When there's an integer overflow in an expression
18169 involving floating point, convert the integers to floating point
18170 so that the resulting value does not suffer from catastrophic
18171 integer truncation. For example, on a 64-bit host (* 4
18172 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18173 Do not rely on undefined behavior after integer overflow.
18175 merge count_size_as_multibyte, parse_str_to_multibyte
18176 * character.c, character.h (count_size_as_multibyte):
18177 Rename from parse_str_to_multibyte; all uses changed.
18178 Check for integer overflow.
18179 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18180 since it's now a duplicate of the other. This is more of
18181 a character than a buffer op, so better that it's in character.c.
18182 * fns.c, print.c: Adjust to above changes.
18184 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18186 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18188 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18190 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18191 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18192 (x_clipboard_manager_save): Now static.
18193 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18195 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18196 (crypto_hash_function): Now static.
18197 Fix pointer signedness problems. Avoid unnecessary initializations.
18199 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18201 * termhooks.h (Vselection_alist): Make it terminal-local.
18203 * terminal.c (create_terminal): Initialize it.
18205 * xselect.c: Support for clipboard managers.
18206 (Vselection_alist): Move to termhooks.h as terminal-local var.
18207 (LOCAL_SELECTION): New macro.
18208 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18209 (symbol_to_x_atom): Remove gratuitous arg.
18210 (x_handle_selection_request, lisp_data_to_selection_data)
18211 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18212 (x_own_selection, x_get_local_selection, x_convert_selection):
18213 New arg, specifying work frame. Use terminal-local Vselection_alist.
18214 (some_frame_on_display): Delete unused function.
18215 (Fx_own_selection_internal, Fx_get_selection_internal)
18216 (Fx_disown_selection_internal, Fx_selection_owner_p)
18217 (Fx_selection_exists_p): New optional frame arg.
18218 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18219 (x_handle_selection_clear): Don't treat other terminals with the
18220 same keyboard specially. Use the terminal-local Vselection_alist.
18221 (x_clear_frame_selections): Use Frun_hook_with_args.
18223 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18225 * xterm.h: Add support for those atoms.
18227 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18229 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18230 (converted_selections, conversion_fail_tag): New global variables.
18231 (x_selection_request_lisp_error): Free the above.
18232 (x_get_local_selection): Remove unnecessary code.
18233 (x_reply_selection_request): Args changed; handle arbitrary array
18234 of converted selections stored in converted_selections.
18235 Separate the XChangeProperty and SelectionNotify steps.
18236 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18237 (x_convert_selection): New function.
18238 (x_handle_selection_event): Simplify.
18239 (x_get_foreign_selection): Don't ignore incoming requests while
18240 waiting for an answer; this will fail when we implement
18241 SAVE_TARGETS, and seems unnecessary anyway.
18242 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18243 (Vx_sent_selection_functions): Doc fix.
18245 2011-05-26 Leo Liu <sdl.web@gmail.com>
18247 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18249 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18251 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18253 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18254 for fringe update if it has periodic bitmap.
18255 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18256 and fringe_bitmap_periodic_p.
18258 * fringe.c (get_fringe_bitmap_data): New function.
18259 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18260 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18261 row. Mark glyph row for fringe update if periodicity changed.
18263 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18264 for fringe update unless it has periodic bitmap.
18266 2011-05-25 Kenichi Handa <handa@m17n.org>
18268 * xdisp.c (get_next_display_element): Set correct it->face_id for
18269 a static composition.
18271 2011-05-24 Leo Liu <sdl.web@gmail.com>
18274 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18276 * fns.c (crypto_hash_function, Fsha1): New function.
18277 (Fmd5): Use crypto_hash_function.
18278 (syms_of_fns): Add Ssha1.
18280 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18282 * gnutls.c: Remove unused macros.
18283 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18284 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18285 Remove macros that are defined and never used.
18286 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18288 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18290 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18291 (Fx_get_selection_internal): Minor cleanup.
18292 (Fx_own_selection_internal): Rename arguments for consistency with
18295 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18297 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18299 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18301 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18303 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18305 * dispnew.c (scrolling_window): Don't exclude the case that the
18306 last enabled row in the desired matrix touches the bottom boundary.
18308 2011-05-21 Glenn Morris <rgm@gnu.org>
18310 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18311 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18312 and add some more files.
18314 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18316 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18317 report_file_error introduced by the change from 2011-05-07.
18319 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18321 * systime.h (Time): Define only if emacs is defined.
18322 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18323 where the include path doesn't have X11/X.h by default. See
18324 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18326 2011-05-20 Kenichi Handa <handa@m17n.org>
18328 * composite.c (find_automatic_composition): Fix previous change.
18330 2011-05-20 Glenn Morris <rgm@gnu.org>
18332 * lisp.mk: New file, split from Makefile.in.
18333 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18334 (shortlisp): Remove.
18335 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18337 2011-05-19 Glenn Morris <rgm@gnu.org>
18339 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18340 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18341 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18342 (lisp): Set the order to that of loadup.el.
18343 (shortlisp): Make it a copy of $lisp.
18344 (SOME_MACHINE_LISP): Remove.
18345 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18346 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18348 2011-05-18 Kenichi Handa <handa@m17n.org>
18350 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18351 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18352 (find_automatic_composition): Mostly rewrite for efficiency.
18354 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18356 * makefile.w32-in: Update dependencies.
18358 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18360 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18361 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18363 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18365 Fix some integer overflow issues, such as string length overflow.
18367 * insdel.c (count_size_as_multibyte): Check for string overflow.
18369 * character.c (lisp_string_width): Check for string overflow.
18370 Use EMACS_INT, not int, for string indexes and lengths; in
18371 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18372 the resulting string length overflows an EMACS_INT; instead,
18373 report a string overflow if no precision given. When checking for
18374 precision exhaustion, use a check that cannot possibly have
18375 integer overflow. (Bug#8675)
18376 * character.h (lisp_string_width): Adjust to new signature.
18378 * alloc.c (string_overflow): New function.
18379 (Fmake_string): Use it. This doesn't change behavior, but saves
18380 a few bytes and will simplify future changes.
18381 * character.c (string_escape_byte8): Likewise.
18382 * lisp.h (string_overflow): New decl.
18384 Fixups, following up to the user-interface timestamp change.
18385 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18386 for UI timestamps, instead of unsigned long.
18387 * msdos.c (mouse_get_pos): Likewise.
18388 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18389 * w32gui.h (Time): Define by including "systime.h" rather than by
18390 declaring it ourselves. (Bug#8664)
18392 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18393 * image.c (clear_image_cache): Likewise.
18395 * term.c (term_mouse_position): Don't assume time_t wraparound.
18397 Be more systematic about user-interface timestamps.
18398 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18399 and sometimes 'EMACS_UINT', to represent these timestamps.
18400 This change causes it to use 'Time' uniformly, as that's what X uses.
18401 This makes the code easier to follow, and makes it easier to catch
18402 integer overflow bugs such as Bug#8664.
18403 * frame.c (Fmouse_position, Fmouse_pixel_position):
18404 Use Time, not unsigned long, for user-interface timestamps.
18405 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18406 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18407 * keyboard.h (last_event_timestamp): Likewise.
18408 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18409 * menu.h (xmenu_show): Likewise.
18410 * term.c (term_mouse_position): Likewise.
18411 * termhooks.h (struct input_event.timestamp): Likewise.
18412 (struct terminal.mouse_position_hook): Likewise.
18413 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18414 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18415 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18416 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18417 what it was before.
18418 * menu.h, termhooks.h: Include "systime.h", for Time.
18420 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18421 Don't assume that the difference between two unsigned long values
18422 can fit into an integer. At this point, we know button_down_time
18423 <= event->timestamp, so the difference must be nonnegative, so
18424 there's no need to cast the result if double-click-time is
18425 nonnegative, as it should be; check that it's nonnegative, just in
18426 case. This bug is triggered when events are more than 2**31 ms
18427 apart (about 25 days). (Bug#8664)
18429 * xselect.c (last_event_timestamp): Remove duplicate decl.
18430 (x_own_selection): Remove needless cast to unsigned long.
18432 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18433 that always fit in int. Use a sentinel instead of a counter, to
18434 avoid a temp and to allay GCC's concerns about possible int overflow.
18435 * frame.h (struct frame): Use int for menu_bar_items_used
18436 instead of EMACS_INT, since it always fits in int.
18438 * menu.c (grow_menu_items): Check for int overflow.
18440 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18442 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18443 Before, the code was not consistent. These values cannot exceed
18444 2**31 - 1 so there's no need to make them unsigned.
18445 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18446 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18447 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18449 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18451 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18452 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18453 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18454 presumably because the widths might not match.
18456 * window.c (size_window): Avoid needless test at loop start.
18458 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18460 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18462 2011-05-12 Drew Adams <drew.adams@oracle.com>
18464 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18466 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18468 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18469 `width' to `bar_area_x' and `bar_area_width', respectively.
18470 (x_scroll_run): Take account of fringe background extension.
18472 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18473 Rename local vars `left' and `width' to `bar_area_x' and
18474 `bar_area_width', respectively.
18475 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18476 background extension.
18478 2011-05-10 Jim Meyering <meyering@redhat.com>
18480 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18482 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18484 * image.c (Finit_image_library): Return t for built-in image types,
18485 like pbm and xbm. (Bug#8640)
18487 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18489 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18491 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18493 * w32console.c (Fset_screen_color): Doc fix.
18494 (Fget_screen_color): New function.
18495 (syms_of_ntterm): Defsubr it.
18497 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18498 unlink the temporary file if Fcall_process didn't create it in the
18500 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18501 child process will be redirected to a file specified with `:file'.
18502 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18503 cue to call_process_cleanup not to close that handle.
18505 2011-05-07 Ben Key <bkey76@gmail.com>
18507 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18508 one of two shell specific rules, either bootstrap-temacs-CMD or
18509 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18510 to the previous implementation of the bootstrap-temacs rule.
18511 The bootstrap-temacs-CMD rule is similar to the previous
18512 implementation of the bootstrap-temacs rule except that it
18513 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18516 These changes, along with some changes to nt/configure.bat,
18517 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18518 earlier fix to add support for --cflags and --ldflags options
18519 that include quotes so that it works whether make uses cmd or
18522 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18524 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18525 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18527 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18528 a string. Handle both cases.
18529 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18530 (Fdbus_register_method): Use Qinvalid_function.
18532 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18534 * makefile.w32-in: Update dependencies.
18535 (LISP_H): Add inttypes.h and stdin.h.
18536 (PROCESS_H): Add unistd.h.
18538 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18540 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18541 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18543 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18545 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18547 * term.c (vfatal): Remove stray call to va_end.
18548 It's not needed and the C Standard doesn't allow it here anyway.
18550 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18551 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18553 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18556 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18558 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18560 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18562 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18564 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18566 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18567 * charset.c (Fdefine_charset_internal): Don't initialize
18568 charset.code_space[15]. The value was garbage, on hosts with
18569 32-bit int (Bug#8600).
18571 * lread.c (read_integer): Be more consistent with string-to-number.
18572 Use string_to_number to do the actual conversion; this avoids
18573 rounding errors and fixes some other screwups. Without this fix,
18574 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18575 (digit_to_number): Move earlier, for benefit of read_integer.
18576 Return -1 if the digit is out of range for the base, -2 if it is
18577 not a digit in any supported base. (Bug#8602)
18579 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18581 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18582 to match comment at start of function. This also removes a
18583 GCC warning about overflow in a 32+64-bit port.
18585 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18587 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18588 Reported by Stefan Monnier in
18589 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18590 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18591 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18593 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18594 (EMACS_UINTPTR): Likewise, with uintptr_t.
18596 * lisp.h: Prefer 64-bit EMACS_INT if available.
18597 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18598 on 32-bit hosts that have 64-bit int, so that they can access
18600 However, temporarily disable this change unless the temporary
18601 symbol WIDE_EMACS_INT is defined.
18603 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18605 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18606 This removes an assumption that EMACS_INT and long are the same
18607 width as pointers. The assumption is true for Emacs porting targets
18608 now, but we want to make other targets possible.
18609 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18610 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18611 In the rest of the code, change types of integers that hold casted
18612 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18613 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18614 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18615 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18616 No need to cast type when ORing.
18617 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18618 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18619 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18620 assume EMACS_INT is the same width as char *.
18621 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18622 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18623 Remove no-longer-needed casts.
18624 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18625 (xg_tool_bar_help_callback, xg_make_tool_item):
18626 Use EMACS_INTPTR to hold an integer
18627 that will be cast to void *; this can avoid a GCC warning
18628 if EMACS_INT is not the same width as void *.
18629 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18630 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18631 (current_message_1, set_message_1):
18632 Use a local to convert to proper width without a cast.
18633 * xmenu.c (dialog_selection_callback): Likewise.
18635 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18636 Also, don't assume VALBITS / RAND_BITS is less than 5,
18637 and don't rely on undefined behavior when shifting a 1 left into
18639 * lisp.h (get_random): Change signature to match.
18641 * lread.c (hash_string): Use size_t, not int, for hash computation.
18642 Normally we prefer signed values; but hashing is special, because
18643 it's better to use unsigned division on hash table sizes so that
18644 the remainder is nonnegative. Also, size_t is the natural width
18645 for hashing into memory. The previous code used 'int', which doesn't
18646 retain enough info to hash well into very large tables.
18647 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18649 * dbusbind.c: Don't possibly lose pointer info when converting.
18650 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18651 Use XPNTR rather than XHASH, so that the high-order bits of
18652 the pointer aren't lost when converting through void *.
18654 * eval.c (Fautoload): Don't double-shift a pointer.
18656 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18658 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18660 * gnutls.c (DEF_GNUTLS_FN):
18661 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18663 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18665 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18668 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18670 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18671 New version that can reserve upto 2GB of heap space.
18673 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18675 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

18739 * process.c: Include lisp.h before w32.h, not after.
18740 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18741 instead of gnutls_record_check_pending.
18743 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18745 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18747 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

18793 rather than `XVECTOR (FOO)->size'.
18795 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18796 inttypes.h, as a gnulib replacement is used if it not available in
18799 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18801 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18802 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18803 of MOST_POSITIVE_FIXNUM. (Bug#8528)

18806 will grow beyond MOST_POSITIVE_FIXNUM.
18807 (decode_coding_emacs_mule): Abort if there isn't enough place in

18811 charbuf for the composition carryover bytes.
18813 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18815 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18816 aborting when %lld or %lll format is passed.
18817 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18818 %llo or %llx format is passed. (Bug#8545)
18820 * window.c (window_scroll_line_based): Use a marker instead of
18821 simple variables to record original value of point. (Bug#7952)
18823 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18824 produced by %s or %c overflows available buffer space. (Bug#8545)
18826 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18828 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18829 (SIZE_MAX): Move defn after all includes, as they might #define it.
18831 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18833 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18835 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18837 * keyboard.c (Qdelayed_warnings_hook): Define.
18838 (command_loop_1): Run `delayed-warnings-hook'
18839 if Vdelayed_warnings_list is non-nil.
18840 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18841 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18843 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18845 * doprnt.c (doprnt): Don't return value smaller than the buffer
18846 size if the message was truncated. (Bug#8545).
18848 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18850 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18851 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18853 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18855 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18857 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18859 * makefile.w32-in: Update dependencies.
18861 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18863 Improve `doprnt' and its usage. (Bug#8545)
18864 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18865 `format_end'. Remove support for %l as a conversion specifier.
18866 Don't use xrealloc. Improve diagnostics when the %l size modifier
18867 is used. Update the commentary.
18869 * eval.c (verror): Simplify calculation of size_t.
18871 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18874 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18876 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18879 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18881 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18882 This makes this file independent of the recent pseudovector change.
18884 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18886 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18888 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18889 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18890 Remove unused local.
18891 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18893 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18894 GCC 4.6.0 optimizes based on type-based alias analysis.
18895 For example, if b is of type struct buffer * and v of type struct
18896 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18897 != &v->size, and therefore "v->size = 1; b->size = 2; return
18898 v->size;" must therefore return 1. This assumption is incorrect
18899 for Emacs, since it type-puns struct Lisp_Vector * with many other
18900 types. To fix this problem, this patch adds a new type struct
18901 vectorlike_header that documents the constraints on layout of vectors
18902 and pseudovectors, and helps optimizing compilers not get fooled
18903 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18904 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18905 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18907 (XSETPVECTYPE): Rewrite in terms of new macro.
18908 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18909 This is a bit clearer, and further avoids the possibility of
18910 undesirable aliasing.
18911 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18912 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18913 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18914 since Lisp_Subr is a special case (no "next" field).
18915 (ASIZE): Now uses header.size rather than size.
18916 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18917 to avoid the hassle of writing XVECTOR (foo)->header.size.
18918 (struct vectorlike_header): New type.
18919 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18920 object, to help avoid aliasing.
18921 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18922 (SUBRP): Likewise, since Lisp_Subr is a special case.
18923 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18924 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18925 (struct Lisp_Hash_Table): Combine first two members into a single
18926 struct vectorlike_header member. All uses of "size" and "next" members
18927 changed to be "header.size" and "header.next".
18928 * buffer.h (struct buffer): Likewise.
18929 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18930 * frame.h (struct frame): Likewise.
18931 * process.h (struct Lisp_Process): Likewise.
18932 * termhooks.h (struct terminal): Likewise.
18933 * window.c (struct save_window_data, struct saved_window): Likewise.
18934 * window.h (struct window): Likewise.
18935 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18936 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18937 * buffer.c (init_buffer_once): Likewise.
18938 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18940 * process.c (Fformat_network_address): Use local var for size,
18943 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18945 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18946 * data.c (atof): Remove decl; no longer used or needed.
18947 (digit_to_number): Move to lread.c.
18948 (Fstring_to_number): Use new string_to_number function, to be
18949 consistent with how the Lisp reader treats infinities and NaNs.
18950 Do not assume that floating-point numbers represent EMACS_INT
18951 without losing information; this is not true on most 64-bit hosts.
18952 Avoid double-rounding errors, by insisting on integers when
18953 parsing non-base-10 numbers, as the documentation specifies.
18954 * lisp.h (string_to_number): New decl, replacing ...
18955 (isfloat_string): Remove.
18956 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18957 (read1): Do not accept +. and -. as integers; this
18958 appears to have been a coding error. Similarly, do not accept
18959 strings like +-1e0 as floating point numbers. Do not report
18960 overflow for integer overflows unless the base is not 10 which
18961 means we have no simple and reliable way to continue.
18962 Break out the floating-point parsing into a new
18963 function string_to_number, so that Fstring_to_number parses
18964 floating point numbers consistently with the Lisp reader.
18965 (digit_to_number): Move here from data.c. Make it static inline.
18966 (E_CHAR, EXP_INT): Remove, replacing with ...
18967 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18968 (string_to_number): New function, replacing isfloat_string.
18969 This function checks for valid syntax and produces the resulting
18970 Lisp float number too. Rework it so that string-to-number
18971 no longer mishandles examples like "1.0e+". Use strtoumax,
18972 so that overflow for non-base-10 numbers is reported only when
18973 there's no portable and simple way to convert to floating point.
18975 * textprop.c (set_text_properties_1): Rewrite for clarity,
18976 and to avoid GCC warning about integer overflow.
18978 * intervals.h (struct interval): Use EMACS_INT for members
18979 where EMACS_UINT might cause problems. See
18980 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18981 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18982 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18984 (offset_intervals): Tell GCC not to worry about length overflow
18985 when negating a negative length.
18987 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18988 (overrun_check_free): Likewise.
18990 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18991 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18994 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18995 (gnutls_make_error): Rename local to avoid shadowing.
18996 (gnutls_emacs_global_deinit): ifdef out; not used.
18997 (Fgnutls_boot): Use const for pointer to readonly storage.
18998 Comment out unused local. Fix pointer signedness problems.
19000 * lread.c (openp): Don't stuff size_t into an 'int'.
19001 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19002 about possible signed overflow.
19004 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19005 (GDK_KEY_g): Don't define if already defined.
19006 (xg_prepare_tooltip): Avoid pointer signedness problem.
19007 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19009 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19010 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19012 * xfns.c (Fx_window_property): Simplify a bit,
19013 to make a bit faster and to avoid GCC 4.6.0 warning.
19014 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19016 * fns.c (internal_equal): Don't assume size_t fits in int.
19018 * alloc.c (compact_small_strings): Tighten assertion a little.
19020 Replace pEd with more-general pI, and fix some printf arg casts.
19021 * lisp.h (pI): New macro, generalizing old pEd macro to other
19022 conversion specifiers. For example, use "...%"pI"d..." rather
19023 than "...%"pEd"...".
19024 (pEd): Remove. All uses replaced with similar uses of pI.
19025 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19026 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19027 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19028 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19029 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19030 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19031 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19033 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19034 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19035 * print.c (safe_debug_print, print_object): Likewise.
19036 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19038 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19039 avoiding the 0 flag, which is not portable.
19040 * process.c (Fmake_network_process): Use pI to avoid cast.
19041 * region-cache.c (pp_cache): Likewise.
19042 * xdisp.c (decode_mode_spec): Likewise.
19043 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19044 behavior on 64-bit hosts with printf arg.
19045 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19046 (x_stop_queuing_selection_requests): Likewise.
19047 (x_get_window_property): Don't truncate byte count to an 'int'
19050 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19051 here, since it parses constructs like leading '-' and spaces,
19052 which are not wanted; and it overflows with large numbers.
19053 Instead, simply match F[0-9]+, which is what is wanted anyway.
19055 * alloc.c: Remove unportable assumptions about struct layout.
19056 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19057 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19058 (allocate_vectorlike, make_pure_vector): Use the new macros,
19059 plus offsetof, to remove unportable assumptions about struct layout.
19060 These assumptions hold on all porting targets that I know of, but
19061 they are not guaranteed, they're easy to remove, and removing them
19062 makes further changes easier.
19064 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19065 This doesn't fix a bug but makes the code clearer.
19066 (string_overrun_cookie): Now const. Use initializers that
19067 don't formally overflow signed char, to avoid warnings.
19068 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19069 can cause Emacs to crash when string overrun checking is enabled.
19070 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19071 multiple of sizeof (EMACS_INT); it need not be, if
19072 alignof(EMACS_INT) < sizeof (EMACS_INT).
19073 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19075 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19077 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19079 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19081 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19082 supposed to be handshaking. (Bug#8556)
19083 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19085 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19087 * lisp.h (Qdebug): List symbol.
19088 * eval.c (Qdebug): Restore global linkage.
19089 * keyboard.c (debug-on-event): New variable.
19090 (handle_user_signal): Break into debugger when debug-on-event
19091 matches the current signal symbol.

19844 Make Emacs functions such as Fatom 'static' by default.
19845 This makes it easier for human readers (and static analyzers)
19846 to see whether these functions can be called from other modules.
19847 DEFUN now defines a static function. To make the function external
19848 so that it can be used in other C modules, use the new macro DEFUE.

19924 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19926 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19927 since callers should never pass a negative size.
19928 Change the signature to match that of plain 'read' and 'write'; see
19929 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19930 * lisp.h: Update prototypes of emacs_write and emacs_read.
19932 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19934 * xdisp.c (redisplay_window): Don't try to determine the character
19935 position of the scroll margin if the window start point w->startp
19936 is outside the buffer's accessible region. (Bug#8468)
19938 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19940 Fix write-region and its subroutines for buffers > 2GB.
19941 * fileio.c (a_write, e_write): Modify declaration of arguments and
19942 local variables to support buffers larger than 2GB.
19943 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19945 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19946 argument, local variables, and return value.
19948 * lisp.h: Update prototypes of emacs_write and emacs_read.
19950 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19952 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19954 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

19958 * xdisp.c (vmessage): Use a better test for character truncation.
19960 * charset.c (load_charset_map): <, not <=, for optimization,

19970 * callint.c (Fcall_interactively): <, not <=, for optimization.
19971 (Fcall_interactively): Count the number of arguments produced,
19972 not the number of arguments given. This is simpler and lets GCC
19973 4.6.0 generate slightly better code.
19975 * ftfont.c: Distingish more carefully between FcChar8 and char.
19976 The previous code passed unsigned char * to a functions like
19977 strlen and xstrcasecmp that expect char *, which does not
19978 conform to the C standard.
19979 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19980 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19981 char * when the C standard requires it.
19983 * keyboard.c (read_char): Remove unused var.
19985 * eval.c: Port to Windows vsnprintf (Bug#8435).
19986 Include <limits.h>.

19988 (verror): Do not give up if vsnprintf returns a negative count.
19989 Instead, grow the buffer. This ports to Windows vsnprintf, which
19990 does not conform to C99. Problem reported by Eli Zaretskii.
19991 Also, simplify the allocation scheme, by avoiding the need for
19992 calling realloc, and removing the ALLOCATED variable.
19994 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19996 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19997 But keep the doprint source code for now, as we might revamp it
19998 and use it again (Bug#8435).
19999 * lisp.h (doprnt): Remove.
20000 * Makefile.in (base_obj): Remove doprnt.o.
20001 * deps.mk (doprnt.o): Remove.
20003 error: Print 32- and 64-bit integers portably (Bug#8435).
20004 Without this change, on typical 64-bit hosts error ("...%d...", N)
20005 was used to print both 32- and 64-bit integers N, which relied on
20006 undefined behavior.
20007 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20008 * lisp.h (error, verror): Mark as printf-like functions.
20009 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20010 Report overflow in size calculations when allocating printf buffer.
20011 Do not truncate output string at its first null byte.
20012 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20013 Truncate the output at a character boundary, since vsnprintf does not
20015 * charset.c (check_iso_charset_parameter): Convert internal
20016 character to string before calling 'error', since %c now has the
20018 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20019 overflow when computing char to be passed to 'error'. Do not
20020 pass Lisp_Object to 'error'; pass the integer instead.
20021 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20022 formatted with plain %d.
20024 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20026 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20028 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20030 * xterm.c (x_catch_errors): Remove duplicate declaration.
20032 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20034 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20036 2011-04-10 Jim Meyering <meyering@redhat.com>
20038 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20039 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20040 return ssize_t not "int", and use size_t as the buffer length.
20041 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20042 * gnutls.h: Update declarations.
20043 * process.c (read_process_output): Use ssize_t, to match.
20044 (send_process): Likewise.

20048 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20050 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20052 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20053 Use unsigned char, to match FcChar8 type definition.
20055 * xterm.c (handle_one_xevent):
20056 * xmenu.c (create_and_show_popup_menu):
20057 * xselect.c (x_decline_selection_request)
20058 (x_reply_selection_request): Avoid type-punned deref of X events.
20060 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20062 Fix some uses of `int' instead of EMACS_INT.

20067 (Fmatch_data): Make some `int' variables be EMACS_INT.
20069 * xdisp.c (display_count_lines): 3rd argument and return value now
20070 EMACS_INT. All callers changed.
20071 (pint2hrstr): Last argument is now EMACS_INT.

20086 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20087 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20089 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20090 (encode_invocation_designation): Last argument P_NCHARS is now
20092 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20093 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20095 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20098 * ccl.c (Fccl_execute_on_string): Declare some variables
20101 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

20116 instead of using internal_with_output_to_temp_buffer.
20117 (Qhelp_form_show): New var.
20118 (syms_of_keyboard): Use DEFSYM macro.
20120 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20154 to system-supplied API.
20156 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20158 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20159 This avoids several warnings with gcc -Wstrict-overflow.
20160 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20161 directly, rather than having caller test rule sign. This avoids
20162 some unnecessary tests.
20163 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20164 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20165 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20167 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20168 (xfont_open): Avoid unnecessary tests.
20170 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20172 * composite.h, composite.c (composition_gstring_put_cache):

20179 by using the new macro.
20181 * textprop.c (set_text_properties_1): Change while to do-while,
20182 since the condition is always true at first.
20184 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20185 (interval_deletion_adjustment): Return unsigned value.
20188 * process.c (list_processes_1, create_pty, read_process_output):

20204 * print.c (print_error_message): Avoid int overflow.
20206 * font.c (font_list_entities): Redo for clarity,
20207 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20209 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20210 (font_score): Avoid potential overflow in diff calculation.
20212 * fns.c (substring_both): Remove var that is set but not used.
20213 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20215 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20217 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20218 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20219 can always succeed if overflow has undefined behavior.
20221 * search.c (boyer_moore, wordify): Remove vars set but not used.
20222 (wordify): Omit three unnecessary tests.
20224 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20225 All callers changed. This avoids the need for an unused var.
20227 * casefiddle.c (casify_region): Remove var that is set but not used.
20229 * dired.c (file_name_completion): Remove var that is set but not used.
20231 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20233 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20234 (Finsert_file_contents): Remove unnecessary code checking fd.
20236 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20237 Check for integer overflow on size calculations.
20239 * buffer.c (Fprevious_overlay_change): Remove var that is set
20242 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20243 Remove vars that are set but not used.
20244 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20245 (timer_check_2): Mark vars as initialized.
20247 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20249 * image.c (lookup_image): Remove var that is set but not used.
20250 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20252 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20253 that are set but not used.
20255 * xfns.c (make_invisible_cursor): Don't return garbage
20256 if XCreateBitmapFromData fails (Bug#8410).
20258 * xselect.c (x_get_local_selection, x_handle_property_notify):
20259 Remove vars that are set but not used.
20261 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20262 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20264 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20265 Remove var that is set but not used.
20266 (scroll_bar_windows_size): Now size_t, not int.
20267 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20268 Check for overflow.
20270 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20271 (map_tty_color) [!defined MSDOS]: Likewise.
20273 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20275 * coding.c: Remove vars that are set but not used.
20276 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20277 All callers changed.

20279 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20280 (decode_coding_charset): Remove vars that are set but not used.
20282 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20283 that is set but not used.
20285 * print.c (print_object): Remove var that is set but not used.
20287 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20288 The gnulib version avoids calling malloc in the usual case,
20289 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20290 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20291 * filelock.c (current_lock_owner): Likewise.
20292 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20293 * sysdep.c: Include allocator.h, careadlinkat.h.
20294 (emacs_no_realloc_allocator): New static constant.
20295 (emacs_readlink): New function.
20296 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20297 ../lib/careadlinkat.h.
20299 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20301 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20302 first non-nil return value).
20304 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20306 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

20316 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20317 and thereabouts. All callers changed.
20318 (get_per_char_metric): Remove parameter `f', unused since
20319 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20321 2011-04-02 Jim Meyering <meyering@redhat.com>
20323 do not dereference NULL upon failed strdup
20324 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20325 (ns_get_family): Likewise.
20327 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20329 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20331 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20333 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

20351 (syms_of_lread): Declare `lexical-binding'.
20353 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20355 * keyboard.c (eval_dyn): New fun.
20356 (menu_item_eval_property): Use it.
20358 * image.c (parse_image_spec): Use Ffunctionp.
20360 * fns.c (concat, mapcar1): Accept byte-code-functions.
20362 * eval.c (Fsetq): Handle lexical vars.
20363 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20364 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20365 (FletX, Flet): Obey lexical binding.
20366 (Fcommandp): Handle closures.
20367 (Feval): New `lexical' arg.
20368 (eval_sub): New function extracted from Feval. Use it almost
20369 everywhere where Feval was used. Look up vars in lexical env.
20371 (Ffunctionp): Move from subr.el.
20372 (Ffuncall): Handle closures.
20373 (apply_lambda): Remove `eval_flags'.
20374 (funcall_lambda): Handle closures and new byte-code-functions.
20375 (Fspecial_variable_p): New function.
20376 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20377 but without exporting it to Lisp.
20379 * doc.c (Fdocumentation, store_function_docstring):
20380 * data.c (Finteractive_form): Handle closures.
20382 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20385 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20387 (exec_byte_code): New function extracted from Fbyte_code to handle new
20388 calling convention for byte-code-functions. Add new byte-codes.
20390 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20392 * alloc.c (Fmake_symbol): Init new `declared_special' field.

20400 * xdisp.c (SCROLL_LIMIT): New macro.
20401 (try_scrolling): Use it when setting scroll_limit.
20402 Limit scrolling to 100 screen lines.
20403 (redisplay_window): Even when falling back on "recentering",
20404 position point in the window according to scroll-conservatively,
20405 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20407 (try_scrolling): When point is above the window, allow searching
20408 as far as scroll_max, or one screenful, to compute vertical
20409 distance from PT to the scroll margin position. This prevents
20410 try_scrolling from unnecessarily failing when
20411 scroll-conservatively is set to a value slightly larger than the
20412 window height. Clean up the case of PT below the margin at bottom
20413 of window: scroll_max can no longer be INT_MAX. When aggressive
20414 scrolling is in use, don't let point enter the opposite scroll
20415 margin as result of the scroll.
20416 (syms_of_xdisp) <scroll-conservatively>: Document the
20417 threshold of 100 lines for never-recentering scrolling.

20424 (message_log_check_duplicate): Remove parameters `prev_bol' and
20425 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20426 (redisplay_internal): Remove parameter `preserve_echo_area',
20427 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20429 * indent.c (Fvertical_motion):
20430 * window.c (window_scroll_pixel_based, Frecenter):
20431 Don't pass `need_y_p' to `move_it_by_lines'.
20433 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20435 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20436 steal a few bits to be more compact.
20437 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20438 Remove unneeded casts.
20440 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20442 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20444 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20445 binding" message (bug#7967).
20447 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20449 Fix more problems found by GCC 4.6.0's static checks.
20451 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20452 Remove unused local var.
20454 * editfns.c (Fmessage_box): Remove unused local var.
20456 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20457 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20458 Omit unused local vars.
20459 * window.c (shrink_windows): Omit unused local var.
20460 * menu.c (digest_single_submenu): Omit unused local var.
20461 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20462 Omit unused local var.
20464 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20465 Don't assume string length fits in int.
20466 (keyremap_step, read_key_sequence): Use size_t for sizes.
20467 (read_key_sequence): Don't check last_real_key_start redundantly.
20469 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20470 instead of alloca (Bug#8344).
20472 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20473 (Fbacktrace_frame): Don't assume nframes fits in int.
20475 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20477 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20480 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20482 * cm.c (calccost): Turn while-do into do-while, for clarity.
20484 * keyboard.c (syms_of_keyboard): Use the same style as later
20485 in this function when indexing through an array. This also
20486 works around GCC bug 48267.
20488 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20490 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

20493 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20495 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20496 This avoids undefined behavior on integer overflow, and is a bit
20497 more convenient anyway since it is compared to a size_t variable.
20499 Variadic C functions now count arguments with size_t, not int.
20500 This avoids an unnecessary limitation on 64-bit machines, which
20501 caused (substring ...) to crash on large vectors (Bug#8344).
20502 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20503 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20504 All variadic functions and their callers changed accordingly.
20505 (struct gcpro.nvars): Now size_t, not int. All uses changed.

20509 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20510 (funcall_lambda, mark_backtrace): Likewise.
20511 * fns.c (concat): Likewise.
20512 * frame.c (x_set_frame_parameters): Likewise.
20513 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20514 0 if not found, not -1. All callers changed.
20516 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20517 (stack_copy_size): Now size_t, not int.
20518 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20520 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

20523 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20524 All callers changed.
20526 * lisp.h (multibyte_char_to_unibyte):
20527 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20528 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20530 * cmds.c (internal_self_insert):
20531 * editfns.c (general_insert_function):
20532 * keymap.c (push_key_description):
20533 * search.c (Freplace_match):
20534 * xdisp.c (message_dolog, set_message_1): All callers changed.
20536 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20538 * keyboard.c (safe_run_hook_funcall): New function.
20539 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20540 don't set the hook to nil, but remove the offending function instead.
20541 (Qcommand_hook_internal): Remove, unused.
20542 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20543 Vcommand_hook_internal.
20545 * eval.c (enum run_hooks_condition): Remove.
20546 (funcall_nil, funcall_not): New functions.
20547 (run_hook_with_args): Call each function through a `funcall' argument.
20548 Remove `cond' argument, now redundant.
20549 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20550 (Frun_hook_with_args_until_failure): Adjust accordingly.
20551 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
20553 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20555 * dispextern.h (string_buffer_position): Remove declaration.
20557 * print.c (strout): Remove parameter `multibyte', unused since
20558 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
20560 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
20561 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20562 All callers changed.
20564 * w32.c (_wsa_errlist): Use braces for struct initializers.
20566 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20567 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20568 All callers changed.
20569 (string_buffer_position): Likewise. Also, make static (it's never
20570 used outside xdisp.c).
20571 (cursor_row_p): Remove parameter `w', unused since
20572 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

20574 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
20575 All callers changed.
20577 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
20579 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

20584 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
20585 (ns_update_auto_hide_menu_bar): New functions.
20586 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

20590 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
20592 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

20605 2011-03-26 Eli Zaretskii <eliz@gnu.org>
20607 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
20608 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
20610 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
20612 * w32.c (read_unc_volume): Use parameter `henum', instead of
20613 global variable `wget_enum_handle'.
20615 * keymap.c (describe_vector): Remove parameters `indices' and
20616 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

20628 * xmenu.c (show_help_event, menu_help_callback):
20629 Adjust calls to `show_help_echo'.
20631 * gtkutil.c (xg_maybe_add_timer):
20632 * keyboard.c (readable_events):
20633 * process.c (wait_reading_process_output):
20634 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
20636 * insdel.c (adjust_markers_gap_motion):
20637 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

20711 2011-03-23 Julien Danjou <julien@danjou.info>
20713 * term.c (Fsuspend_tty, Fresume_tty):
20714 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20715 * window.c (temp_output_buffer_show):

20720 * editfns.c (save_excursion_restore):
20721 * cmds.c (internal_self_insert):
20722 * callint.c (Fcall_interactively):
20723 * buffer.c (Fkill_all_local_variables):
20724 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20726 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20727 unconditionally since it does the check itself.
20729 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20731 Fix more problems found by GCC 4.5.2's static checks.
20733 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20734 the first time through the loop, since we know p0 < p1 then.
20735 This also avoids a gcc -Wstrict-overflow warning.
20737 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20738 leading to a memory leak, possible in functions like
20739 load_charset_map_from_file that can allocate an unbounded number
20740 of objects (Bug#8318).
20742 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20743 that could (at least in theory) be that large.
20745 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20746 This is less likely to overflow, and avoids undefined behavior if
20747 overflow does occur. All callers changed. Use strtoul to scan
20748 for the unsigned long integer.
20749 (pint2hrstr): Simplify and tune code slightly.
20750 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20760 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20763 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20765 * process.c (Fmake_network_process): Use socklen_t, not int,
20766 where POSIX says socklen_t is required in portable programs.
20767 This fixes a porting bug on hosts like 64-bit HP-UX, where
20768 socklen_t is wider than int (Bug#8277).
20769 (Fmake_network_process, server_accept_connection):
20770 (wait_reading_process_output, read_process_output):
20773 * process.c: Rename or move locals to avoid shadowing.

20780 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
20781 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
20783 Make tparam.h and terminfo.c consistent.
20784 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20785 Include tparam.h instead, since it declares them.
20786 * cm.h (PC): Remove extern decl; tparam.h now does this.
20787 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20788 * terminfo.c: Include tparam.h, to check interfaces.
20789 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20790 (tparam): Adjust signature to match interface in tparam.h;
20791 this removes some undefined behavior. Check that outstring and len
20792 are zero, which they always are with Emacs.
20793 * tparam.h (PC, BC, UP): New extern decls.
20795 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20796 (xftfont_open): Rename locals to avoid shadowing.
20798 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
20799 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
20800 (OTF_TAG_SYM): Omit macro if not needed.
20801 (ftfont_list): Remove unused local.
20802 (get_adstyle_property, ftfont_pattern_entity):
20803 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
20804 Rename locals to avoid shadowing.
20806 * xfont.c (xfont_list_family): Mark var as initialized.
20808 * xml.c (make_dom): Now static.
20810 * composite.c (composition_compute_stop_pos): Rename local to
20812 (composition_reseat_it): Remove unused locals.
20813 (find_automatic_composition, composition_adjust_point): Likewise.
20814 (composition_update_it): Mark var as initialized.
20815 (find_automatic_composition): Mark vars as initialized,
20816 with a FIXME (Bug#8290).
20818 character.h: Rename locals to avoid shadowing.
20819 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20820 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20821 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20822 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20823 to avoid shadowing.
20825 * textprop.c (property_change_between_p): Remove; unused.
20827 * intervals.c (interval_start_pos): Now static.
20829 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
20831 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
20832 Rename locals to avoid shadowing.
20834 * sound.c (wav_play, au_play, Fplay_sound_internal):
20835 Fix pointer signedness.
20836 (alsa_choose_format): Remove unused local var.
20837 (wav_play): Initialize a variable to 0, to prevent undefined
20838 behavior (Bug#8278).
20840 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20842 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20844 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20845 clobbering (Bug#8298).
20846 * sysdep.c (sys_subshell): Likewise.
20847 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20849 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20850 This should get cleaned up, so that child_setup has the
20851 same signature on all platforms.
20853 * callproc.c (call_process_cleanup): Now static.
20854 (relocate_fd): Rename locals to avoid shadowing.
20856 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20858 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20859 not to be necessary, and produces flickering.
20861 2011-03-20 Glenn Morris <rgm@gnu.org>
20863 * config.in: Remove file.
20865 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20867 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20868 are now in src/globals.h.
20869 (syms_of_minibuf): Remove spurious & from previous change.

20969 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
20970 (Fdefvar): Rewrite so as not to use empty "else".

20984 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20985 some of which prompt warnings from gcc -Wbad-function-cast.
20986 (Fformat_time_string, Fencode_time, Finsert_char):
20987 (Ftranslate_region_internal, Fformat):

21018 avoids undefined behavior in theory.
21020 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21022 Use functions, not macros, for up- and down-casing (Bug#8254).
21023 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21024 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21025 to use the following functions instead of these macros.
21026 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21027 EMACS_INT, since callers assume the returned value fits in int.
21028 (upcase1): Likewise, for UPCASE_TABLE.
21029 (uppercasep, lowercasep, upcase): New static inline functions.
21030 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21039 which gcc can warn about.
21040 (regex_compile, re_match_2_internal): Mark locals as initialized.
21041 (RETALLOC_IF): Define only if needed.
21042 (WORDCHAR_P): Likewise. This one is never needed, but is used
21043 only in a comment talking about a compiler bug, so put inside
21044 the #if 0 of that comment.
21045 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21046 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21049 * search.c (boyer_moore): Rename locals to avoid shadowing.

21064 Rename locals to avoid shadowing.
21065 (Fvertical_motion): Mark locals as initialized.
21067 * casefiddle.c (casify_object, casify_region): Now static.
21068 (casify_region): Mark local as initialized.

21072 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21073 New macros, so that the caller can use some names other than
21074 gcpro1, gcpro2, etc.
21075 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21077 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21078 argument, for consistency with GCPRO2_VAR, etc: it is now the
21079 prefix of the variable, not the variable itself. All uses
21081 * dired.c (directory_files_internal, file_name_completion):
21082 Rename locals to avoid shadowing.
21084 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21085 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21086 dired.c's scmp function, had undefined behavior.
21087 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21088 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21089 * buffer.h: ... to here, because these macros use current_buffer,
21090 and the new implementation with inline functions needs to have
21091 current_buffer in scope now, rather than later when the macros
21093 (downcase, upcase1): New static inline functions.
21094 (DOWNCASE, UPCASE1): Reimplement using these functions.
21095 This avoids undefined behavior in expressions like
21096 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21097 from race conditions in accessing the global variables
21098 case_temp1 and case_temp2.
21099 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21100 * lisp.h (case_temp1, case_temp2): Remove their decls.
21101 * character.h (ASCII_CHAR_P): Move from here ...
21102 * lisp.h: ... to here, so that the inline functions mentioned
21103 above can use them.
21105 * dired.c (directory_files_internal_unwind): Now static.
21107 * fileio.c (file_name_as_directory, directory_file_name):
21108 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21110 (file_name_as_directory): Use const pointers when appropriate.
21111 (Fexpand_file_name): Likewise. In particular, newdir might
21112 point at constant storage, so make it a const pointer.
21113 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21114 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21116 (Fset_file_times, Finsert_file_contents, auto_save_error):

21121 to avoid shadowing.
21123 * marker.c (bytepos_to_charpos): Remove; unused.
21125 * lisp.h (verify_bytepos, count_markers): New decls,
21126 so that gcc does not warn that these functions aren't declared.
21128 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21129 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21130 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21131 (copy_text): Remove unused local var.
21133 * filelock.c (within_one_second): Now static.
21134 (lock_file_1): Rename local to avoid shadowing.
21136 * buffer.c (fix_overlays_before): Mark locals as initialized.
21137 (fix_start_end_in_overlays): Likewise. This function should be
21138 simplified by using pointers-to-pointers, but that's a different
21140 (switch_to_buffer_1): Now static.
21141 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21142 (report_overlay_modification): Rename locals to avoid shadowing.
21144 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21145 Fix pointer signedness issue.
21146 (sys_subshell): Mark local as volatile if checking for lint,
21147 to suppress a gcc -Wclobbered warning that does not seem to be right.
21148 (MAXPATHLEN): Define only if needed.
21150 * process.c (serial_open, serial_configure): Move decls from here ...
21151 * systty.h: ... to here, so that they can be checked.
21153 * fns.c (get_random, seed_random): Move extern decls from here ...
21154 * lisp.h: ... to here, so that they can be checked.
21156 * sysdep.c (reset_io): Now static.
21157 (wait_for_termination_signal): Remove; unused.
21159 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21160 (copy_keymap_item, append_key, push_text_char_description):
21162 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21163 (DENSE_TABLE_SIZE): Remove; unused.
21164 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21165 (describe_map_tree):
21166 Rename locals to avoid shadowing.
21168 * keyboard.c: Declare functions static if they are not used elsewhere.
21169 (echo_char, echo_dash, cmd_error, top_level_2):
21170 (poll_for_input, handle_async_input): Now static.
21171 (read_char, kbd_buffer_get_event, make_lispy_position):
21172 (make_lispy_event, make_lispy_movement, apply_modifiers):
21173 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
21174 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
21175 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
21176 (read_key_sequence, read_char): Mark locals as initialized.

21253 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
21254 These macros can no longer be used for assignment.
21256 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

21312 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
21314 Improve quality of tests for time stamp overflow.
21315 For example, without this patch (encode-time 0 0 0 1 1
21316 1152921504606846976) returns the obviously-bogus value (-948597
21317 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
21318 reports time overflow. See
21319 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
21320 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
